Liz is watching a film at the cinema.

The film started at 1430
The film is 105 minutes long.
When the film ends, Liz takes 20 minutes to get to the bus stop.
A bus leaves the bus stop at 1645
Does Liz get to the bus stop in time to get this bus?
You must show all your working.

Answer 1

Yes she dose 1430+105+20=1555 hence there she made it to the bus stop on time.

Answer 2

Yes, she does

Explanation:

105min=1h 45min

14h 30min + 1h 45min= 16h 15min

16h 15min + 0h 20min=16h 35min

16h 45min - 16h 35min= 10min

So, the answer is yes, she does and she still has 10 minutes free.
