kow [346]

Answer:

C. 7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

distance = speed × time

300t = 350(t -1)

300t = 350t -350 . . . . eliminate parentheses

350 = 50t . . . . . . . . . . add 350-300t

7 = t . . . . . . divide by 50

The trip out took 7 hours.
