For a given speed, the distance traveled varies directly with the time. Kate's school is 5 miles away from her home and it takes her 10 minutes to reach the school. If josh lives 2 miles from school and travels at the same speed as Kate, how long will it take him to reach the school?

Solution:

The distance: D

The time taken: t

The formula is

D = K*t

When D = 5 miles, t = 10 min, K = 0.5

Wehn D = 2 miles, t = D/K = 2/0.5 = 4 min

So it takes 4 min for josh to reach the school
