Question 965986: A plane is travelling at 180 meters per second. How many minute will it take the plane to travel 800km Answer by tenkun(12) (Show Source):
You can put this solution on YOUR website! speed of a plane = 180 m/s = 180* 18/5
= 648 km/h
( to convert m/s to km/h we should multiply by 18/5)
now
to travel 648 km the time taken by a plane = 1 h
to travel 800 km the time taken by a plane = 1/648 *800
= 1 h 19 min
= 79 min
hence solved
