Question

Trains, A and B are travelling on the same route
heading towards the same destination. Train B has
already covered a distance of 220 km before train A
started. The two trains meet each other 11 hours after
the start of train A. Had the trains been travelling
towards each other (from a distance of 220 km), they
would have met after one hour. What is the speed of
train B in km/h?
(a) 100 km/h (b) 180 km/h (c) 116 km/h
(d) Date inadequate​

Answer 1

Answer:

100 km/h

let speed of b be x

let speed of a be y

11x-11y=220...1

x+y=220....2

now solve for x and y
