Question

An airplane flies 810 km in 1.5 hours. How far will the plane fly into. Two hours if it maintains the same airspeed

Answer 1

First you have to find the speed using distance/time:

810/1.5=540

Speed=540

Then to find distance use speed(time)

540(2)=1080

So your answer is

Distance= 1080km

Answer 2

It would help to first find the unit rate. We know that the plane flies 810 km per 1.5 hours. Divide by 1.5 on both sides:

810/1.5 = 540 km/hour

Then, multiply both the hour and the distance by 2:

540 * 2 = 1080 km/2 hours.
