Carl is eating lunch at his favorite cafe when his friend Isaac calls and says he wants to meet him. Isaac is calling from a city 175 miles away, and wants to meet Carl somewhere between the two locations. Isaac says he will start driving right away, but Carl needs 35.0 min to finish his lunch before he can begin driving.
Isaac plans to drive at 70.0 mph, and Carl plans to drive at 55.0 mph. Ignore acceleration and assume the highway forms a straight line.
How long will Isaac be driving before he meets Carl?
