Two cars started simultaneously towards ...

Two cars started simultaneously towards each other from towns A and B which are 480 km apart.It took first car travelling from A to B 8 hours to cover the distance and second car travelling form B to A in 12 hours.Determine when do the car meet after starting and at what distance from town A.Assuming that both the cars travelled with constant speed.

Text Solution

Verified by Experts

Velocity of car from `A=(480)/8=60//hour`
Distance travelled from `A=60t`velocity of car from
`B=(480)/(12)=40km//hour`
Distance travelled from `B=42t`
Let the two cars meet at t hour then `60t+40t=480 km`
`:. T=(480)/(60+40)=4.8 =hours`
the distance `s=v_(A)xxt=60xx4.8=288km`.
