The running time for movie a is 40 minutes more than twice the running time for movie

PtichkaEL [24]

3b - a = 45
a = 2b + 40

Solve simultaneously.

3b - (2b + 40) = 45
3b - 2b - 40 = 45
b = 45 + 40
b = 95min (1 hour 35 min)

a = 2 (95) + 40
a = 230min ( 3 hour 50 min)

$5^2 = 5*5 =25$

Refine:

$x \leq 25$
