Question

A man walks at a rate of 3 miles per hour and johs at. a rate of 5 miles per hour. he walks and jaogs a total distance of 3.5 miles in 0.9 hoirs how long does the man jog?

Answer 1

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
