Question

an aeroplane flies 3500 km in the same time, the train covers 600 km. If the speed of the aeroplane is 50 km/hr more than five times the speed of the train, what are the speeds of the train and the aeroplane? ​

Answer 1

Time=Distance/Speed

Since time for both is same we have

3500/5x+50=600/x

35/5(x+10)=6/x

7x=6x+60

so train speed is x= 60 and

plane speed=350.

Answer 2

Given,

let the speed of the aeroplane be 50×5=250km/hr.

then the speed of the Train is 50km/hr
