Question

Mohan had 3 hours of free time in the evening. He spent 45 minutes on home-work and 112 hours on games. How much free time was he left with? (Write the answer as a fraction.)

Answer 1

Given :

Total number of free time = T = 3 hours

Time spend on home work = $t_1$ = 45 minutes

Time spend on games = $t_2$ = 112 minutes

To Find :

How much free time was left

Solution :

Let The hours of free time left = $t_3$ hours

∵ Total number of free time = Time spend on home work + Time spend on games + The hours of free time left

Or,   T = $t_1 + t_2 + t_3$

Or,   $t_3$  = T - ( $t_1 + t_2$ )

Or,   $t_3$  = 3 hours - ( 45 min + 112 min )

Or,   $t_3$  = 3 hours - ( 157 min )

Or,   $t_3$  = 3 × 60 min - 157 min                              ( ∵ 1 hours = 60 min )

Or,   $t_3$  = 180 min - 157 min

∴      $t_3$  = 23 min

Hence, The free time that was left with Mohan is 23 minutes   Answer
