A car passes point A driving at a constant rate of 60 km per hour. A second car, travelling at a constant rate of 75 km per hour, passes the smae point A a while later and then follows the first car. It catches the first car after travelling a distance of 75 km past point A. How many minutes after the first car passed point A did the second car pass point A?
Remember : Distance / rate = time
Car 1 travels for 75 km / 60 km /hr = 1.25 hours
Car 2 travels for 75 km/75 km/hr = 1 hour
1.25 hr - 1 hr = .25 hr which is 15 minutes
Remember : Distance / rate = time
Car 1 travels for 75 km / 60 km /hr = 1.25 hours
Car 2 travels for 75 km/75 km/hr = 1 hour
1.25 hr - 1 hr = .25 hr which is 15 minutes
