During a 50km race on level ground, Andrea runs from kilometer 10 to kilometer 15 with an average velocity of 6.02 m/s. How long does it take her to run that part of the race?
Answer - 13.8m
- SHOW WORK PLEASE :)
 
well we all know that

average speed = total distance traveled / total time of travel

thus total time of travel = total distance traveled / average speed

= [ 15 - 10 ] X 1000 / (6.02) 60

in the above equation we multiply the numerator by 1000 as the distances are in kilometers and the denominator by 60 as the time is to be reported in minutes

thus total time of travel = 13.8 minutes
