Price per hour of first case :

$P_1 = 24 + 9a$ ( Here, a is number of hours )

Price per hour of second case :

$P_2 = 18 + 11b$ ( Here, b is number of hours )

Let, after x hours both company charges the same.

$P_1=P_2\\\\24+9x = 18 + 11x\\\\2x=6\\\\x = 3\ hours$

Hence, this is the required solution.
