Grubhub Change Delivery Address: How to Edit

Yes, you can change your Grubhub delivery address, but only if your order hasn’t been accepted by the restaurant yet. Once a restaurant confirms your order, the address is locked and you’ll need to contact Grubhub support to request a change. Below, we cover the exact steps, time limits, and what to do when things go wrong.

Formula

The calculator works out your average pace and speed from a finish time and distance. Pace is the time it takes to cover one unit of distance, and speed is the distance covered per hour. The formulas are:

Pace (min/km) = Finish time (minutes) ÷ Distance (km)

Speed (km/h) = Distance (km) ÷ (Finish time (minutes) ÷ 60)

Variables:

• t – finish time in minutes (e.g., 50 minutes)
• d – distance in kilometers (e.g., 10 km)
• pace – minutes per kilometer (min/km)
• speed – kilometers per hour (km/h)

Worked Example

Using the default values: t = 50 minutes, d = 10 km.

1. Pace = 50 ÷ 10 = 5.00 min/km
2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows 5.00 min/km and 12.00 km/h for these inputs.

When to Use This Calculator

Use this tool when you train for a race, plan a run or bike ride, or need to estimate how long a trip will take at a given speed. It works for any distance unit as long as you convert everything to the same unit (e.g., miles to kilometers or minutes to hours).

How to Read the Results

A lower pace (min/km) means faster speed. For example, a 5 min/km pace equals 12 km/h, while a 6 min/km pace equals 10 km/h. Speed is the inverse of pace – if you know one, you can calculate the other.

Common Mistakes

• Mixing units: If your distance is in miles, convert to kilometers (1 mile = 1.60934 km) or use minutes per mile for pace.
• Forgetting to convert time: Always use minutes, not hours, in the pace formula.
• Rounding too early: Round only the final result to avoid errors.

Limitations of the Formula

This formula assumes constant speed and does not account for terrain, stops, or elevation changes. It gives an average, not a real-time measurement. For real-world use, GPS watches and apps provide more accurate data.

Frequently Asked Questions

Can I change my Grubhub delivery address after ordering? Yes, but only if the restaurant hasn’t accepted your order yet. Once accepted, you must contact Grubhub support, and they may or may not be able to change it depending on the driver’s status.

How long do I have to change my address? The window is typically a few minutes – from the moment you place the order until the restaurant confirms it. This can be as short as 30 seconds or as long as a couple of minutes.

What happens if I enter the wrong address? If the order is already being delivered, you can try to contact the driver through the app to inform them of the correct address. If that fails, contact Grubhub support – they may cancel the order and issue a refund, but it’s not guaranteed.

Does Grubhub charge a fee to change the address? Grubhub does not advertise a fee for changing an address, but if the new address is farther away, the delivery fee may increase. You’ll see the updated total before confirming the change.

Can I change the address after the driver picks up the food? Technically, you can request a change, but the driver is not obligated to deliver to a different location. The safest route is to contact the driver directly and ask if they are willing to go to the new address, possibly with an extra tip.

What if I’m ordering for someone else? You can change the address before the restaurant accepts the order, just like a normal order. After acceptance, you’ll need to contact support, and the same rules apply.
