Question

A car escapes from Police. The police start chasing 54 minutes later. Police travel 12% faster. How many minutes will it take to catch up?

SO FAR I got that
D=(x)(t+54) for the escaped car
AND
D=(1.12x)(4)

Can someone help me through the process and give me the correct answer? thanks!
(x)(t+54) = (1.12x)t
tx + 54x = 1.12tx
.12tx = 54x
.12t = 54
t = 450

The actual value of x does not matter.
