How far will a migrating duck fly in 7 hours at an average speed of 21 miles per hour

But I doubt you look like Ariana Grande.

Distance = speed multiplied by time

distance(mi) = speed(mi/hr) * time(hr) = 21*7 = 147 mi

Yes, I believe you are Kim K.

To find out how far a migrating duck will fly in 7 hours at an average speed of 21 miles per hour, you can simply multiply the speed by the time.

Distance = Speed * Time

In this case, the speed is 21 miles per hour and the time is 7 hours, so the calculation would be:

Distance = 21 miles/hour * 7 hours

To find the result, you can calculate:

Distance = 147 miles

Therefore, the migrating duck will fly approximately 147 miles in 7 hours at an average speed of 21 miles per hour.
