=2×2-3×2×(-1)
= 4+6
=10
Answer:
so, 10 laps in 25 mins we want to make mins=1 so
10/25=2/5 times 5/5=2/5
if you multiply 2/5 by 2/2 then you get 4/10 and 4/10=0.4
the runner can run 0.4 or 2/5 lap in 1 minute

To find out the time in between a different time you can add in segments, you can add 15min to 2:45, to make it 3:00, then add 60 more minutes to make it 4:00, so now we have 75 min, then add 20 minutes to get the time to 4:20 pm, you then add up all the segments, which equal 95 minutes. In hours it would be 1 hour, and 35 minutes. Hope you understand that, of not, tell me, and ill fix it and make it more understandable.
