In a 1000 m race, A beats B by 100 m and B beats C by 100 m. In the same race, by how many meters does A beat C?  Choose one
A) A)190m  B) B)829m  C) C)822m  D) D)929m  E) E)132mj
By the time A covers 1000 m, B covers  (1000 - 100)=

<output>900</output>
900 m.   So, the ratio of speeds of A and C=   1000/900 * 1000/900 = 1000/810 So, by the time A covers 1000 m, C covers 810 m.   So in 1000 m race A beats C by 1000 - 810= 
<gadget id="calculator">1000 - 810</gadget>
<output>190</output>
190 m.   190mnswer:190m
<result>A</result>
In a 1000 m race, A beats B by 100 m and B beats C by 100 m. In the same race, by how many meters does A beat C?
