Hey there !
The airplane travels with uniform motion (=constant velocity), so we can calculate the distance it travels using the formula for uniform motion:
where
v is the speed of the plane
t is the time elapsed
In this problem:
v = 5000 mi/h is the speed of the plane
t = 1 h 45 min is the time elapsed
We have to convert this time into hours; we know that 45 minutes corresponds to 3/4 of an hour, that is 0.75 hours. So, the time here is
Therefore, the distance covered is: 8750 miles
