Question

The speed of the two trains are in the ratio 4:5 .if the speed of the first train is 64 km/h , what is the speed of the other train​

Answer 1

let the speed be X

therefore, 1 train = 4x

..2 train = 5x

4x+5x = 64

9x= 64

X=64/9

X=7.1

Speed of second train is 5*9.01 = 45.05 km/hr

• speed of first train is 64km/hr
