The two cars leave from two places at the same time and meet three hours later. The speed ratio of car a and car B is 5:4. The distance between the two cars is 270 km. What's the speed of the two cars
Total speed of two vehicles = 270 / 3 = 90 km / h
Car a = 90 * (5 / 9) = 50 km / h
Vehicle B = 90 * (4 / 9) = 40 km / h
The speed of the two cars is 50 km / h and 40 km / h respectively
A and B leave from two places at the same time and meet in three hours. The speed ratio of a and B is 5:4. The distance between the two places is 270 km. Find the speed of the two cars
270 km / 3 h = 90 km / h
The sum of speed is: 90 km / h
The speed ratio is 5:4
So: a speed: 90 km / h × 5 / (5 + 4) = 50 km / h
B speed: 90 km / h × 4 / (5 + 4) = 40 km / h
The speed ratio of the two cars is known to be 5:4. How many kilometers do the two cars travel per hour?
thank you!
Speed sum = 270 / 1.5 = 180 km / h
Express speed = 180 × 5 / 9 = 100 km / h
Idle speed = 180-100-80 km / h
[I hope I can help you]
The speed ratio of the two cars is known to be 5:4. How many kilometers do they travel per hour
Such as the title
270 ÷ 1.5 ÷ (5 + 4) × 5 = 100 km / h
100 △ 5 × 4 = 80 km / h
