Two cars leave town at the same time in the same direction. One travels 35km/hr and the 40 km/hr. In how many hours will they  be 15 miles apart?

anonymous · Answer

I am a bit lazy now to do unit conversion, but, let's say that we are dealing only with kilometers. In 1 hour, the first car will travel 35 km and the other 40 km. So their distance will be 5. Similarly for 2 hours: the distance travelled will be 80 - 70 = 10. The distance will be 5*t, where t is in hours. Do the unit conversion first to miles/hour and try to find the same relation between them :-)

I think it will 3.106856*t, t in hours. So, it should be somewhere near 5 hours :-)
