Question

At a hot air balloon festival. Mohamed's balloon is at an altitude of 40m and rises 10m/min  Dana's balloon is at an altitude of 165m and descends 15m/min.
b) What will be the altitude?

hintHint:

given, the initial heights and rate of increment (or)decrement of balloon .

The correct answer is: In 5 mins both balloons will be at same altitude of 90m


    b) now find height of any balloon at t (as both will be at same height at t)
    Ans :
    The altitude will be  90m.
    Explanation :-
    Let the time be t min at which both balloons have the same height .
    find the height of balloons at time t = 5 min
    Height of both balloons = 40 m + 10m/min (5 min) = 40m + 50m = 90 m.
    ∴In 5 mins both balloons will be at same altitude of 90m .
