Arturiano [62]

Answer: Bob can make it to base camp in about 1.6 hours.

If I am understanding the problem correct, Bob must drive 10 km to get to the road through the desert. Then, 45 km on the road. And finally, another 10 km off the road to get to the base camp.

We end to find the time for each section of the trip.

Start with the formula: d = rt or t = d/r

Now, we can divide to determine the amount of time for each section.

1) 10 / 30 = 0.333 hours
2) 45/50 = 0.9 hours
3) 10/30 = 0.333 hours

Add up all the times, and you get about 1.6 hours.
