Question 1203959: At noon, a cargo plane leaves Ling airport and heads towards Shangxu 500km away at 180km/h. At 1:00pm, a jet takes off from Ling airport and flies on the same course at 450km/h. What time will the jet overtake the cargo plane? Found 4 solutions by mananth, josgarithmetic, math_tutor2020, ikleyn:Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! At noon, a cargo plane leaves Ling airport and heads towards Shangxu 500km away at 180km/h.
At 1:00pm, a jet takes off from Ling airport and flies on the same course at 450km/h
Since the jet leaves one hour later , the cargo plane would have traveled 180 km
speed of cargo plane 180 km/h
speed of jet = 450 km/h
They are flying in the same direction
Effective speed = 450 - 180 = 270 km/h
catch up time = catch up distance / catch up speed
time = 180/270 =2/3
Tje jet catches up after 2/3 hours = 40 minutes.
The jet will overtake the cargo plane at 1:40pm.
You can put this solution on YOUR website! That is one-hour of cargo plane travel time before the jet began its travel. The amount of distance to be closed for catch-up is 180 kilometers.
