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:
1.8
laps per minute

The boy who swims at a faster rate is
L
. (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

I'm confused with Henry. PLEASE HELP!!

Answer 1

Henry is : y = 1.6x.....where y = # of laps and x = time in minutes.
So if you want to know how many laps Henry can do in 1 minute, sub in 1 for x.
y = 1.6(1)
y = 1.6.....so he can swim 1.6 laps per minute
