Xiao Wang rode a bicycle and Xiao Li rode a motorcycle. At the same time, they set out from two places 100km away, facing each other. After meeting each other on the way, they continued to move forward, turned their backs and started at the same time In the last three hours, they were 314km apart. Xiao Wang traveled 14km per hour, and Xiao Li how many km per hour?
124km/h
(314 + 100) / 3-14 = 124 is the motorcycle so fierce-
A. The distance between two places is 60 kilometers. A starts from a by bike, and B starts from B by motorcycle. If a starts 1 hour and 40 minutes earlier than B, then a meets B 3 hours after starting. After meeting, the two continue to move forward. When a arrives at B, B just arrives at a, and asks for the speed of a and B
Let a's velocity be x km / h and B's velocity be y km / h, then 3x + (3 − 123) y = 603xy = 43yx, and the solution is x = 12Y = 18 or x = 60y = − 90 (not the problem, rounding off). A: A's velocity is 12 km / h and B's velocity is 18 km / h
A and B are 120 kilometers apart. A starts from a by bike and B by motorcycle. They all go in the same direction. A starts earlier than B
(1) How many hours after B set out to catch up with a? (2) B returned immediately after arriving at B, where did B meet a on the way?
A: 15 km / h, B: 60 km / h. how long does a start earlier than B
He was killed
If it's two hours
First question:
Set t hours to catch up
15T+（15*2）=60T
T=2/3
60*2/3=40
Party A and Party B ride bicycles from two places 65km apart at the same time and meet each other in 2 hours. If Party A rides 2.5km more than Party B per hour, what's the speed of Party B? If they walk in the same direction, Party A will catch up with Party B in a few hours
Speed sum: 65 △ 2 = 32.5 (km / h) speed of a: (32.5 + 2.5) △ 2 = 17.5 (km / h) speed of B: 32.5-17.5 = 15 (km / h) born for dream^_ ^I wish you progress in your study! If you agree with my answer, please click the "adopt as satisfactory answer" button in time
