Explanation / Answer

If d is the distance, r is the rate of travel and t is the time, then d = rt.

(a) since d = rt, on dividing both the sides by r , we have d/r = rt/r or. t = d/r.

(b) At an averate rate of travel of 60 mph, the time taken to cover a distance of 210 miles is t = d/r = 210/60 = 3.5 hours. Thus, the answer is 3.5 hours.
