HURRY
Answers
Answer:
The race is 111.6m long
Step-by-step explanation:
8hurdles spaced 12.3m part means 7
spaces that are 12.3m in length; 7*12.3= 86.1
Add to this the distance to the first hurdle and the distance from the last hurdle
86.1+15+10.5= 111.6m
Given : event requires each runner to jump 8 hurdles that are spaced 12.3 meters apart.
there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line,
To Find : how long is the race
Solution:
point to be take care here :
if 2 hurdles are spaced at x m
Then Distance = (2 - 1) x = m
if 3 hurdles are spaced at x m each
Then Distance = (3 - 1) x = 2x m
runner to jump 8 hurdles that are spaced 12.3 meters apart.
Distance between 8 hurdles
= (8 - 1) * 12.3
= 7 * 12.3
= 86.1 m
there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line,
Hence length of race = 15 + 86.1 + 10.5
= 111.6 m
