How do I solve the following question link: ( https://ibb.co/mdTj45 )

Do I just work out the total distance walked by each man and put it in a ratio?

After a very brief revise at dt graphs I think the answer is 14:13.

Hmm... I'm not too sure about that answer. I got 7:6, dyou want me to explain it?

Ok, but it said that both m and n are double digit integers.
Note that in a speed (or velocity) time graph, the area under the curve represents the area.

Find the area under both graphs (of man 1 and man 2). Cut up the dotted lines to form shapes i.e. trapeziums, rectangles, etc.

Man 1: area = distance = 35m
Man 2: area = distance = 32.5m

So ratio m:n = 35:32.5 = 14:13.
