You can put this solution on YOUR website! Ms. Driva Reck drove from her home to a service station at 48 km/h.
She returned home by bicycle at 16 km/h.
The entire trip took 4 hours. How far was the service station from Ms. Reck's home?
:
Let d = distance to the service station
:
Write a time equation: time = dist/time
:
to time + return time = 4 hrs + = 4
Multiply by 48, to clear the denominators:
48* + 48* = 4(48)
d + 3d = 48(4)
4d = 192
d = 192/4
d = 48 km

Check this
48/48 + 48/3 =
1 + 3 = 4
