Question 764295: two cars will run for 10 kilometers,car A started 7 1/2 kilometers ahead, car B started at 0kilometers, what will be the speed of two cars if they reach 10 kilometers at the same time? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! two cars will run for 10 kilometers,
car A started 7 1/2 kilometers ahead,
car B started at 0 kilometers,
what will be the speed of two cars if they reach 10 kilometers
at the same time?
:
Not enough information to find the actual speed, but we can find
the relationship between the two speeds =
Cross multiply
2.5B = 10A
B = 10A/2.5
B = 4A
:
B's speed is 4 time A's
