If a plane is going 110 mph how can it go for 21/2 hours

Multiply the speed per hour by the number of hours:

110 x 2 1/2 = 275 total miles.

275 miles

Step-by-step explanation:

Assuming it is 2 1/2

To find the distance, take the rate and multiply by the time

We know the rate is miles per hour and the time is in hours so the units match

d = r*t

   = 110 * 2 1/2

Changing the mixed number to an improper fraction

    110 * 5/2

    275 miles

part 1 answer = 8

part 2 answer = 72
