Question

Alana goes to see a concert that lasts for 2 hours and 10 minutes.
It ends at half past 8.

What time did the concert start?

Answer 1

Answer:

6: 20

Step-by-step explanation:

(half past 8 = 8:30)

First, we can calculate what 2 hours earlier was.

When it ends at 8 : 30, two hours before that would have been 6 : 30 (8 - 2 = 6)

Then, 10 minutes before that would be 6 : 20 (30 - 10).

So, from working backwards, the concert started at 6 : 20

Answer 2

Answer:

The time of the concert starting is 6:20

Step-by-step explanation:

- It ends at half past 8

half an hours is 30mins

This means 8:30

- 2 hours and 10 minutes

2 hours before 8:30 is 6:30

10 minutes before 6:30 is 6:20
