Answer:
12: 10 pm
Step-by-step explanation:
In the question, we need to backtrack time. But first, let's figure out the amount of time he spent in total.
2h(time spent going to the place) + 35m(time spent at the place) + 30m( back)
2h = 120m
120 + 35 + 30 = 185m
Now, it said he ended at 3:15pm
so 3:15 - 185 = 0: 10 which is 12: 10 PM
