Question

The equation y = 1.6x represents the number of laps Henry can swim over time, where y is the number of laps and x is time in minutes. The table shows the number of laps Larry can swim over time.



How many laps can each boy complete per minute, and who can swim laps at a faster rate?



Henry: laps per minute



Larry: laps per minute



The boy who swims at a faster rate is . (Type H for Henry or L for Larry)




Larry
Time (min) 2.5 4 5.5 8
Laps completed 4.5 7.2 9.9 14.4

Answer 2

For Henry: y = 1.6 * x
The slope is 1.6 which means he can swim 1.6 laps per minute.

For Larry:
Time (min) 2.5 4 5.5 8
Laps completed 4.5 7.2 9.9 14.4
Differences in time: 1.5 1.5 2.5
Differences in laps: 2.7 2.7 4.5
Slope = 2.7/1.5 = 27/15 = 9/5 = 1.8

Larry does 1.8 laps per minute.

Larry swims faster.
