A team of swimmers is training for a swim meet. The table shows the number of laps each person has swum so far and how long the laps took. [the picture attachment of the graph]

The relationship between time and the number of laps is not proportional across all swimmers. Which two swimmers swam at the same rate (had time and laps in the same proportion)?
[the picture attachment of the answer choices]

D. --- Johnathan and Seth

Step-by-step explanation:

1. Look at the table. See which ones look somewhat like they have the same rate.

2. Investigate. If you see that Johnathan has 2 laps in 4 minutes, and Seth has 3 laps in 6 minutes, they look the same

3. See if they are the same. If you check it: 2/4 ?= 3/6, Simplify and: (2/2)/(4/2) and (3/3)/(6/3) simplify to 1/2 and 1/2. 1/2=1/2, so they have the same ratio/rate.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
