Question

Laurie was scuba diving. Each time she dove 5 feet deeper, she would stop and clear her ears. After Laurie had checked her instruments 3 times, she was at her maximum depth of 60 feet. Which expression best represents Laurie’s maximum depth?

Answer 1

Laurie dove each time feet deeper=5

checked her instruments =3 times>(3×)

maximum depth of Laurie=60

3×5x=60

5x=60/3

5x=20

x=20/5

x=4

We will cross check the answer,

3×5(4)=60

5×4=20

3×20=60

Hence,60 is the answer
