Answer:
She traveled part of the way by bus, which arrived at the train station just in time for Wendy to complete her journey by train.
The bus averaged 40 mi/h, and the train averaged 80 mi/h.
The entire trip took 4 1/2 hours.
How long did Wendy spend on the train?
:
let d = distance traveled by train
the total distance was given as 260 m, therefore:
(260-d) = distance by bus
:
Write a time equation; time = dist/speed
train time + bus time = 4.5 hrs
Step-by-step explanation:
d%2F80 + %28%28260-d%29%29%2F40 = 4.5
multiply by 80, cancel the denominators and you have
d + 2(260-d) = 80(4.5)
d + 520 - 2d = 360
d - 2d = 360 - 520
-d = -160
d = 160 mi by train
"How long did Wendy spend on the train?"
160/80 = 2 hrs on the train
:
Confirm this answer by finding the time on the bus
100/40 = 2.5 hrs, added to the train time = 4.5 hrs
