- In a 1000 m race A beats B by 100 m and C by 200 m. By how much can B beats C in a race of 1350 m?
Question 1:
In a 1000 m race A beats B by 100 m and C by 200 m. By how much can B beats C in a race of 1350 m? A. 125 m
B. 130 m
C. 140 m
D. 150 m
Feedback If A run 1000 meters then B runs 900 meters and C runs 800 meters.
? B runs 1350 meters while C will run 800 * 1350/ 900 = 1200 meters
Hence, B can beat C by (1350 – 1200) = 150 m
? B runs 1350 meters while C will run 800 * 1350/ 900 = 1200 meters
Hence, B can beat C by (1350 – 1200) = 150 m
