Water flows from a showerhead at a rate of 24^-1 gallons per second. How many gallons do you use when taking a 15-mintue shower? a 20- minute shower?​

15 min=37.5 gal., 20 min=50 gal.

Step-by-step explanation:

Hey! This question can be tricky at first look. So what we’re going to do first is find 24^-1. This would be .0416 rounded to the thousandths place. We are rounding because it is a repeating decimal and it goes on forever or for a while at least. Now we know that .0416 gallons flow each second.

Next, we will multiply by 60 to find how much flows each minutes. We do this because there are 60 seconds in a minute. We then get 2.5 gallons.

We then multiple by the number of minutes which in this case is 15 and 20.

2.5x15= 37.5 gallons

2.5x20=50 gallons

Sorry if I did anything wrong! If you have any questions, I’m sorry because I have messaging turned off! :(

Hope this helps!

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
