Answer:
1 hr 15 mins or 1.5 hours
Explanation:
Time spent by Narayan going to his grandmother's house = 2 1/2 hrs
Therefore, time spent by Narayan going to his grandmother's house in mins.
=2hrs 30 mins
= (2×60mins)+30mins. =120mins+30mins
=150 mins
Time waiting at traffic signals= 1/2 of the time he spent going to his grandmother's house.
= 1/2 of 150 mins
= 150/2
= 75 mins
Therefore, 75mins in hours.
= 75/60
= 1.15hrs / 1hr15mins
Therefore, Narayan spent 1.15 hours waiting at the traffic signals.
