At the same time, car a and car B are 360 kilometers apart and meet at 4 o'clock. Car a travels 35 kilometers per hour. How many kilometers per hour does car B travel?
360 divided by 4 = 90
So the total speed is 90
Car B: 90-35 per hour = 55
A travels 55 kilometers per hour and B 45 kilometers per hour. The two cars meet each other 5 hours after driving. How many kilometers is the distance between a and B?
Distance: 5 × (55 + 45) = 500 km
I wish you progress in your study
Two cars leave 378 kilometers apart at the same time. Car a travels 50 kilometers per hour and car B 55 kilometers per hour. When is the time to drive
Two cars leave 378 kilometers apart at the same time. Car a travels 50 kilometers per hour and car B 55 kilometers per hour. When do car a and car B meet on the way?
378÷(50+55)=3.6
A: meet in 3.6 hours
The distance between the two cities is 180 kilometers. Two cars start from the two cities at the same time. Car a travels 35 kilometers per hour, and car B travels 55 kilometers per hour. How long will they meet after they leave? (to calculate)
180/（35+55）=2
Primary school students study hard!
