Question

A passenger plane made a trip to Las Vegas and back. On the trip there it flew 432 mph and the return trip it went 480 mph. How long did the trip there take If the return trip took nine hours?

Answer 1

The total distance cover in the trip to Las Vegas and back is 8640 miles

Explanation:

Given as :

The on trip speed of plane = 432 mile per hour

The return trip speed of plane = 480 mile per hour

The time taken in return trip = 9 hour

So,let the distance cover in return trip = D miles

∴ Distance = speed × time

Or, D = 480 mile per hour × 9 hour

So , D= 4320 miles

I.e Total distance of the trip = 2 × 4320 = 8640 miles

Hence The total distance cover in the trip to Las Vegas and back is 8640 miles Answer
