Question 963426: Adam ran a 15-kilometer race. He completed the race in 1.6 hours. Adam’s speed for the first kilometer can be represented by the function d = 9.2h, where d is distance in kilometers and h is time in hours. Was Adam’s average speed for the first kilometer of the race faster or slower than his average speed for the entire race? Justify your answer. Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! Distance=rate x time, so for the first kilometer Adams rate was 9.2 km/hr.
For the entire race, his rate was 15km/1.6 hrs=9.375 km/hr, so his average for the entire race was faster than his rate for the first kilometer
