Question

The speed of an airplane is 1,240 km per hour. Find the distance covered by the airplane in 3 hours and 20 minutes. Also, express the distance in scientific notation.

Answer 1

Dear student,

According to the question,
time = 3 hours 20 mins = $3\frac{20}{60}=3\frac{1}{3}=\frac{10}{3}\mathrm{hour}$
Speed = 1240 km/hr
So distance = $speed\times time=1240\times \frac{10}{3}=4133.33=413333\times {10}^{-2}$km
