Walt rode his bike from home to the bicycle repair shop and then walked home.
He averaged 18 km/h riding and 6 km/h walking.
If his total time was one hour, how far was it to the shop from Walt's home?
:
Write a time equation, time = dist/speed
:
Let d = the distance from home to shop
:
Ride time + walk time = 1 hour
+ = 1
multiply by 18, to clear the denominators, results:
d + 3d = 18
4d = 18
d = 18/4
d = 4.5 mi to the shop
:
:
Check this by finding the times
4.5/18 = .25 hrs
4.5/6 = .75
-----------------
total time: 1.0 hrs
