An airplane flies from Morocco to France. The trip takes two hours and 15 minutes. If the plane flies at a constant speed of 500 miles per hour, how far is it from Morocco to France? Choose the closest answer. 1,125 kilometers 1,699 kilometers 1,547 kilometers 1,811 kilometers

The nearest value is 1811 km

Explanation:

This is an exercise in kinematics, with uniform movement

v = x / t

Let's reduce time to seconds

t1 = 2 h (3600s / 1h) = 7200 s

t2 = 15 min (60s / 1min) = 900 s

The total time is

t = t1 + t2

t = 7200 + 900

t = 8100 s

We calculate the distance

x = v t

We reduce speed to mile / h to km / s

v = 500 mile / h (1,609 km / 1 mills) (1h / 3600s)

v = 0.2235 km / s

x = 0.2235 8100

x = 1810.5 km

The nearest value is 1811 km
