one car travels 50 miles per hour and another one travels at 55 miles per hour. they start atbthe same point ans at the same tim
ICE Princess25 [194]

Think:  (distance traveled by faster car) - (distance traveled by slower car) = 35 mi.

Using the formula distance = rate times time, we get for the faster car:

(55 mph)(t)

and for the slower car we get (50 mph)(t), so that

(55 mph)(t) - (50 mph)(t) = 35 mi.  This can be simplified as follows:

(5 mph)(t) = 35 mi.  Dividing both sides by 5 mph, we get t = (35 mi) / (5 mph).

Then t = 7 hours.  The two cars will be 35 miles apart, going in the same direction, after  7 hours.
