Maria rode her bike 20 miles in 120 minutes. Assuming she rides at a constant speed, a) how far would she ride 24 minutes?

b) how long did it take her to ride 3 miles?

Part A:

Divide

120 / 20 = 6 minutes per mile

Divide

24 / 6 = 4 miles

Part B:

Multiply

6 * 3 = 18 minutes

Best of Luck!

Step-by-step explanation:

If 10 oz. box costs $3.50 and a 16 oz. box costs $5.00 and she collected $97.50 we can represent an expression that relates for how many money Jillian made:

(1)

where x is the number of 10 oz. boxes and y is the number of 16 oz. boxes.

She sold 24 boxes therefore:

(2)

We can right equation in terms of y and substitute it into equation 1:

(2)

Solve for x:

Jillian sold 15 10oz. boxes
