### Instruction: a 270 m long train running at the speed of 120 km / hr crosses another train running in opposite direction at the speed of 80 km / hr in 9 sec . what is the length of the other train ? Let's write a Python program.### Response: n0 = 270.0
n1 = 120.0
n2 = 80.0
n3 = 9.0
t0 = n1 + n2
t1 = t0 * 0.2778
t2 = n3 * t1
answer = t2 - n0
print(answer)
