A soda machine takes 3 seconds to fill a 15-ounce cup. If t represents the time in seconds, which equation can you use to find how long it takes the machine to fill a 40-ounce cup?

Question

CLEAR CHECK

3 • 15 = 40t

3/15
= t/40

5/t
= 40

t/40
= 15/3

Answer 1

None of the equations provided are correct. To find how long it takes the machine to fill a 40-ounce cup, you can set up a proportion:

3 seconds / 15 ounces = t seconds / 40 ounces

This can be simplified to:

t = (3 seconds / 15 ounces) * 40 ounces

t = (3/15) * 40

t = 8 seconds
