The speed of the car and motorcycle is 5:4. The two cars leave from a and B at the same time. They meet at 24 kilometers from the midpoint. How many kilometers are there between a and B?
The speed of the car and motorcycle is 5:4. The two cars leave from a and B at the same time. They meet at 24 kilometers from the midpoint. How many kilometers are there between a and B?
24÷【1/2-4/（4+5）】
=24÷【1/2-4/9】
=24÷1/18
=432 km
A and B are facing each other, driving for 4 hours and meeting at a distance of 4 kilometers from the midpoint. B is slower than a, how much more does a drive per hour than B?
The average answer is 2 kilometers per hour
Can you understand it?
Let Bo = OC = 4km, C as the meeting point and o as the midpoint
So BC is the distance that a takes more than B in four hours, a total of 8km,
The rest you get?
Five year old math problem: Party A and Party B start from each other at the same time. After four hours, they meet at a distance of 4km from the midpoint. Party B is slower than Party A,
B is slower than a, so B walks 4 * 2 = 8km less than a
After 4 hours, the speed of B is 8 / 4 slower than that of a = 2 km / h
