Note that the first question is division, not division. A divided by b equals a÷b, and a divided by b equals b divided by a, that is, b ÷ a.

(60.5+65)×60×2.5= 18825

Note that the second question is 60.5 meters and 65 meters per minute, and the time given is hours, which needs to be converted into 60×2.5= 150 minutes.
