Question

Jack had 4 hours of school. He spent 45 minutes in the library and 12 hour on a science lecture and had a lunch break of 25 minutes. How much time is left for the school to get over? (Write the answer as a fraction.)

Answer 1

Step-by-step explanation:

School time - 12 hrs = 720 mins

Science - 4 hrs = 240 mins

Library - 45 min

Lunch - 25 min

Library + lunch -70 mins

$720 - (240 + 70) \\720 - 310 \\ = 410$

410 mins - 6 hrs 50 mins

$6 \times \frac{50}{60} \\6 \times \frac{5}{6} \\ = \frac{41}{6}$
