### Instruction: two trains a and b starting from two points and travelling in opposite directions , reach their destinations 9 hours and 4 hours respectively after meeting each other . if the train a travels at 110 kmph , find the rate at which the train b runs . Let's write a program.### Response: import math
n0 = 9.0
n1 = 4.0
n2 = 110.0
t0 = n0 / n1
t1 = math.sqrt(max(0, t0))
answer = n2 * t1
