Marco calculated that he could run a 5K race in 28 minutes. His actual time was 26 minutes. What is the percent error in his estimation? Round to the nearest tenths place. I NEED THIS ASAP PLZ HELP

Answer 1

Answer:

7.70%

Step-by-step explanation:

Total length of race = 5k

Actual time taken to run the race = 26 minutes

Marcos time = 28 minutes

Percentage error = difference in value / actual time × 100

= (28 - 26) / 26 × 100

= 2 / 26 × 100

= 0.077 × 100

= 7.70%
