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 1

so for harry create a table to compare

Time (mins) 2.5 | 4 | 5.5 | 8
| | |
Laps 1.6 x 2.5 | 1.6 x 4 | 1.6 x 5.5 | 1.6 x 8


compare to you know Henry laps per minute = 1.6 x 1

Larry to find laps per minute, pick 2 points from the table
and find the slope...

the faster is the highest laps per minute score
