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.
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
