---------------
Going the same direction, the speed of one relative to the other is the difference, 47-32 = 15 mph.
69/15 = 4.6 hours

Car[1] = Speed[1] = 32mi/hr
Car[2] = Speed[2] = 47mi/hr

Remember for Speed = Distance / time

And Distance = Speed*time (working Eqn)

We both cars will be apart by 69 miles in t (hours)

So we need to subtract their speed in relevance to the time when they're apart 69 miles.

Putting into equation:

t=4.6 hours or 4 hours and 36 minutes

Let's check:

Difference:
