Car a and car B travel from a and B at the same time. They meet in 5 hours. After meeting, car a goes to B in 4 hours. At this time, car B is 60 kilometers away from A. how many kilometers are there between a and B?
A: the distance between a and B is 300 km
A and B two cars from a, B two opposite lines, a and B speed ratio of 5:4. After meeting a and B continue to line, a to B, B from a still 60 kilometers, after meeting B line
How many kilometers?
Please write the formula
2400km
A and B drive from two places at the same time. A travels 60 kilometers per hour and B 52 kilometers per hour. The two places meet 16 kilometers away from the center to find the distance between the two places
Encounter time = 16 × 2 ÷ (60-52) = 4 (hours)
Distance: 4 × (60 + 52) = 448 (km)
