Let,

Lee’s class size = L

Fred’s class size = F

 

We are told that Lee’s fifth-grade class has 1.0 times as many students as Fred’s

Therefore, L = 1F

L = F

 

Question A. If there are a total of 60 students, how many students does Fred’s class have? 

Total number of students = 60

L + F = 60

 

Since L = F

L + F = F + F + 60

F + F = 60

2F = 60

F = 60/2

F = 30

Therefore, if there are a total of 60 students, Fred’s class has 30 students.

 

 

QUESTION B. If there are a total of 60 students, how many students does Lee’s class have?

Total number of students = 60

L + F = 60

 

Since L = F

L + F = L + L + 60

L + L = 60

2L = 60

L = 60/2

L = 30

Therefore, if there are a total of 60 students, Lee’s class has 30 students.

Bill and Joe leave their house at the same time heading in opposite directions. If Bill is driving three times faster than Joe a
Arisa [49]

The problem statement gives you the relationship between their speeds, and it gives you information you can use to find their total speed. You solve this by finding the total speed, then the proportion of that belonging to Bill.

The total speed is (120 mi)/(3 h) = 40 mi/h.

The speed ratio is ...

... Bill : Joe = 3 : 1

so the speed ratio Bill : Total is ...

... 3 : (3+1) = 3:4.

Bill's speed is (3/4)×(40 mi/h) = 30 mi/h.
