Question 1045581: Use the data from Luis's bike ride to answer the following:
Position (m) 0.00 105 270 400 540 600
Time (s) 0.00 30 60 90 120 150

a. What was Luis's speed (in meters per second) for the entire ride from 0 to 150s?
b. What was Luis's speed (in meters per second) between 60 and 90s?
c. During which 30s interval did Luis have the greatest speed? Calculate his speed during this interval.
Answer by robertb(5830) (Show Source): You can put this solution on YOUR website!
a. Total distance traveled is 600 meters, for a total of 150 seconds.
===> Luis' speed is 600/150 = 4 meters per second.
b. Between 60 and 90s, he traveled 400 - 270 = 130 meters. His speed is then
130/30 = 4.33 meters per second (to three significant figures).
c. Since time is scaled by every 30 seconds, his greatest speed is between the 30 and 60s, with
a speed of 165/30 = 5.5 meters per second.
