an air force plane flew to istanbul and back.  the trip there took 5 hours and the trip back took 4 hours.  what was the air force plane's average speed on the trip there if it averaged 240 mph on the return trip?

anonymous · Answer

Trip back: S= 240mph,   T= 4h
Dist= s X T
= 240 X 4
=960 m

anonymous · Answer

Av speed = total dist/total time taken
=(960 x 2)/ (5+4)
= 213 1/3 mph

anonymous · Answer

Sorry....av speed to istanbul= Dist / Time
=960/5
= 192 mph
