Two cars drive from a to B at the same time. Car a travels 35 kilometers per hour, while car B travels 40 kilometers per hour. After four fifths of an hour, how many kilometers is the distance between the two cars How many kilometers are the two cars apart?

A: 35 × 4 / 5 = 28 km
B: 40 × 4 / 5 = 32 km
So the distance is 32-28 = 4km

3) A car from a to B, three fifths of the whole journey is less than 5 kilometers, at this time has been 124 kilometers, a, B distance______ Kilometer

3) A car from a to B, three fifths of the whole journey is less than 5 kilometers, at this time has been 124 kilometers, a, B distance___ 322.5___ Kilometer
