    take the number of hours the man walks as x

    and the number of hours the man jogs as y

    therefore one eqn can be 3x + 4y = 3.5

    and the other one is x+y = 0.9

    on solving this simultaneous linear eqns. we will get x as 0.1 and y as 0.8

    and as y is the number of hours jogged by the man

    the number of hours jogged by the man is 0.8 hours
