Question

Two trains x and y start from mumbai and delhi towards delhi and mumbai respectively after passing each other they take 12 h 30 min and 8 h to reach delhi and mumbai respectively if the train from mumbai is moving at 60 km/ hr then find the speed of the other train

Answer 1

Speed of x /speed of y =
$\sqrt{t2 \div t1}$


60 / y =
$\sqrt{8 \div 25 \div 2}$

60/y =sqrt of 16/25

60/y = 4/5

Y = 75 km/hrs
