<PRE><B>Question 1203688</B>
At noon, a cargo plane leaves Angama airport and heads towards Bamburi 500 km away at 180 km/h. 

At 1.00pm the plane has traveled 180 kms

At 1.00 pm, a jet takes off from Angama and flies on the same course at 450 km/h.

The distance to overtake is 180 kms

The effective speed = 450-180 = 270 km/h  ( Since both are flying in the same durection)

Time = distance /speed 

=180/270= 2/3  hour 

The jet overtakes the cargo plane after 40 minutes


 What time will the jet overtake the cargo plane?

The jet will overtake the cargo plane at 1:40 pm.
