Ryan drinks 1 1/2 liters of water every 3/4 of an hour at a constant rate. How many liters of water does Ryan drink in one hour
melamori03 [73]

Answer:

<em>2 litres of water</em>

Step-by-step explanation:

If Ryan drinks 1 1/2 liters of water every 3/4 of an hour at a constant rate, this can also be expressed as;

1 1/2 litres = 3/4 hour

To get the amount of litres Ryan drank for 1 hour

x = 1 hour

Divide both equations

(3/2)/x = (3/4)/1

3/2x = 3/4

2x * 3 = 3 * 4

6x = 12

x = 12/6

x = 2

<em>Hence Ryan drinks 2 litres of water in an hour</em>

For each equation below , determine the value of y if x = 2 .
Fynjy0 [20]
You simply plug in the value of x in each equation to find y.

1)
y = 7 - 3(2)
y = 7 - 6
y = 1

2)
y = 18/2
y = 9

hope this helped, blessings!
