Man jogs 10 km/hr. to stadium.
He drives back at 60 km/hr. and saves one hour.
How far was the stadium.
:
First find the times, write a distance equation, dist = speed * time
Let t = his jogging time
then
(t-1) = his driving time
:
jog dist = drive dist
10t = 60(t-1)
10t = 60t - 60
60 = 60t - 10t
60 = 50t
t =
t = 1.2 hrs to jog it, then obviously, .2 hrs to drive it
:
Find the dist:
10 * 1.2 = 12 km to the stadium
Check the dist
.2(60) = 12 km also
