           SPEED        TIME        DISTANCE
Day 1        r           x+3          120
Day 2        r            x           110

Each day same rate r.

120%2F%28x%2B3%29=110%2Fx

The information looks suspicious: 3 hours longer to travel 10 km farther...?

Let's see....

rate = distance/time

Let x be the number of hours driving the second day; then x+3 is the number of hours driving the first day.

The rates both days are the same:

120%2F%28x%2B3%29+=+110%2Fx
120x+=+110x%2B330
10x+=+330
x+=+33

So he drove x = 33 hours the second day and x = 36 hours the first day........

What planet is he driving on where a day has more than 36 hours?
