Answer:

7 hours.

Step-by-step explanation:

The outward trip took 5 hours.

We now calculate the distance of this trip:

Speed = distance / time, so

Distance = speed * time.

= 14 * 5 = 70 miles.

So the time for the return journey =  distance / speed

= 70 / 35

= 2 hours.

So the time for the entire trip

= 5 + 2 = 2 hours.
