Answer:
Step-by-step explanation:
Given that Alice and Bob race two toy trains around a circular track. The trains move in the same direction and they meet every 120 seconds. If Alice's and Bob's toy trains move in opposite directions, at constant rates, they meet every 30 seconds
Circular track is 1800 m.
Let speed be x and y respectively
When in same direction relative speed = x-y and when in opposite directions =x+y
30(x+y) = 1800
x+y= 60
120(x-y) = 1800
x-y = 15
Solving x = 37.5 m/hr and y = 12.5 per hour.
