Question

Jax started his homework at 3:15 pm and finished it at 5:30 pm. How long did he take to finish the homework?

• A. 1 hour 45 mins
• B. 2 hours 15 mins
• C. 2 hours
• D. 1 hour 15 mins

Answer 1

The correct option is B 2 hours 15 mins

Start time = 3:15 pm
End time = 5:30 pm

3:15 pm - 5:30 pm
$\to$ 3:15 pm - 5:15 pm and
5:15 pm - 5:30 pm

Time elapsed from 3:15 pm to 5:15 pm
= 5 hours - 3 hours
= 2 hours

Time elapsed from 5:15 pm to 5:30 pm
= 30 mins - 15 mins
= 15 mins

$\therefore$ Total time elapsed = 2 hours 15 mins

$\therefore$ Jax took 2 hours 15 mins to finish his homework.
