Answer:
275 minutes 12 seconds
Step-by-step explanation:
Given that :
slowest running time per mile = 9 minutes and 14 seconds
fastest running time per mile = 7
minutes and 58 seconds.
To estimate the time taken to run 16 miles ;
Obtain the Average of the two run times :
(9 minute 14 seconds) + (7 minutes 58 seconds) = 17 minutes 12 second
Hence it takes an average of 17 minutes 12 seconds per mile
Time taken to run 16 miles :
((17 * 60) + 12) * 16 = 16512 seconds
16512 / 60 = 275 minutes 12 seconds
