Answer:
The world record for the 200-m dash will be set at 18.0 seconds in the year 2920.
Step-by-step explanation:
To find what year the record will be 18 seconds, substitute 18 in for R, and solve for t.
-0.0028t + 20.8 = R
-0.0028t + 20.8 = 18
-0.0028t = -2.8
t = 1000
The record for the 200-m dash will be 18 seconds after 1000 years. To find which year this record will be set in, add 1000 to the original date, 1920.
1920 + 1000 = 2920
The answer is 76 & 14, hope this helps.
