Question

In a 400 meter race, 4 runners pass a baton as each of them runs 100 meters of the race. The table shows the split times for the first 3 runners of a relay team. Suppose the team has set a goal of running the race in 210 seconds. Solve the equation

(53,715 + 51.3 + 52.62) + n = 210 to find the number of seconds, n, within which the 4th runner must finish for the team to meet its goal.

Answer 1

The 4th runner must complete their 100-meter segment of the relay race in 52.365 seconds or less for the team to meet their goal of running the race in 210 seconds.

Step-by-step explanation:

To find the number of seconds, n, within which the 4th runner must finish for the team to meet their goal of completing a 400-meter relay race in 210 seconds, we can solve the equation (53.715 + 51.3 + 52.62) + n = 210.

• First, we add the split times for the first three runners: 53.715 + 51.3 + 52.62 = 157.635 seconds.
  
• Next, we subtract this sum from the total goal time: 210 - 157.635 = 52.365 seconds.
  
• The 4th runner must therefore complete their segment of the race in 52.365 seconds or less for the team to achieve their goal.

Answer 2

Since the equation is addition, reverse it into subtraction. 210-53.715-51.3-52.62= 52.365. You can add 53.715 by 51.3 by 52.62 by 52.365 to check your answer, and it will be 210 so the 4th runner ran 52.365 seconds.

i also got this question but i figured it out lol
