    Increased difficulty level....

    A and B are participating i a 1500 m race. A gives B a lead of 50 m and beats him by 10 m in a 500 m race. If B completes the 1500 m race in 44 minutes, then A finishes the race.....minutes before B.
    1) 2 minutes
    2) 12 minutes
    3) 14 minutes
    4) 20 minutes

    "A gives B a lead of 50 m and beats him by 10 m in a 500 m race"
    => this means, in the same amount of time the distances travelled by A and B are as follows:
    distance travelled by A = 500m
    distance travelled by B = 450-10 = 440m

    => (Speed of A)/(Speed of B) = 500/440 = 50/44
    As the speed and time are inversly proportional for the same amount od distance,
    => (Time taken by A)/(Time taken by B) = 44/50
    => (Time taken by A) = (44/50)(Time taken by B)

    This relation holds good for any race, if the speeds of A and B are assuned constant.

    "B completes the 1500 m race in 44 minutes"
    => A completes this in = (44/50)*44 = this comes approximately to be 39 minutes
    A completes the race 44-39 = 5 minutes before B

    Answer is not available in the options, pl check
