The distance between the two places is 350 meters. Car a and car B drive from the two places at the same time and meet each other 3.5 hours later

The distance between the two places is 350 meters. Car a and car B drive from the two places at the same time and meet each other 3.5 hours later

The two cars run from two places 350km apart and meet two hours later
Party A and Party B two cars leave at the same time from two places 350 km away, go opposite each other, and meet two hours later. The speed ratio of a and B cars is 2:3. How many kilometers per hour can a and B cars travel? (use X to set,)

Suppose a travels 2x kilometers per hour, then 3x kilometers per hour
2(2x+3x)=350
5x=175
x=35
So a 2 * 35 per hour = 70 kilometers
B: 3 * 35 per hour = 105 km

Two cars a and B set out at the same time from a and B, which are 350 kilometers apart, and they went in opposite directions. They met five hours later
How many kilometers does car a travel per hour and car B travel per hour?

350 △ 5-31 = 39 (km)

A and B start at the same time from two places 300 kilometers apart, and run in opposite directions. After two hours of meeting, it is known that the speed of car a is 140% of that of car B,
What are the speeds of a and B cars?

300÷2÷（140% +1）
= 150 ÷ 2.4
=Vehicle B speed 62.5km
62.5 × 140% = 87.5km vehicle speed
