Question

If something starts at 10.25 and lasts for 45 minutes what time does it finish

Answer 1

Well you add 25 to the 45 if its 10:25 oh clock it makes it 11:10.

(The 25 + 45= 70, there is only 60 minutes in a hour so it makes it 11:10.), [25 + 45, the 2 and 4 add up to a 6 but the two 5 makes it 10 so it = 11:10, Remember: 60ty minutes is a hour so 70 is 10 minutes past a hour so it makes it 11:10.]

Sense I believe your talking about a clock problem, and not another kind of problem it may be wrong if your talking about a not clock problem hope this helps :)

[Btw I putted this in the easiest terms I could think of, and the other part of the explanation you don't really need it, it just explains a little more :) hope this helps] If it doesn't make sense just tell me I'll try to help out some more :)
