Mark's model train can go 1/3 laps around its track in 2 minutes. If it runs at the same speed, how many laps can the train go in 9 minutes?

1.5 laps

Step-by-step explanation:

You can use a proportion to solve this problem.

2 minutes is to 1/3 lap and 9 minutes is to x laps.

2/(1/3) = 9/x

Cross multiply:

2x = 9 * 1/3

2x = 3

x = 1.5

1.5 laps

ok

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
