Practicing Success
In 800 m. race, A defeats B by 40 m and in 500 m race, B defeats C by 5 m. Find the distance by which A defeats C in 200 m race? |
11.9 meter 1.27 meter 1.19 meter 12.7 meter |
11.9 meter |
Ratio of distance covered : - A : B B : C 800 : (800-40) 500 : (500-5) 800 : 760 500 : 495 20 : 19 100 : 99
Then, A : B : C = 2000 : 1900 : 1881 ↓ x \(\frac{1}{10}\) 200 : 190 : 188.1 Therefore, In 200 m race, A will defeat C by = 200 - 188.1 = 11.9 m |
