Answer:

$\frac{4548}{1}$ liters per hour.

Step-by-step explanation:

Given : A hose fills a tank at a rate of 20 gallons per minute.

To find : What is the rate in liters per hour?

Solution : We have given

A tank can fill hose in 1 minute = 20 gallon .

1 gallon = 3.79 liters.

20 gallon = 20 * 3.79 = 75.8 liters.

20 gallon = 75 .8 liters.

So,

A tank can fill hose in 1 minute = 75.8 liters.

A tank can fill hose in 60 minute = 75.8 * 60 liters = 4548 liters.

A tank can fill hose in 1 hour = 4548 liters.

Rate = $\frac{4548}{1}$ liters per hour.

Therefore, $\frac{4548}{1}$ liters per hour.

First, you need to know how many gallons will be in the tank after 1 hour. So:

Esther drove to work in the morning at an average speed of 45 miles per hour. She returned home in the evening along the same ro

nydimaria [60]

The key is Esther travelled the same distance - x - in both her morning and evening commute.

45(time she took in the morning, or p) = x
30(time she took in the evening, or q) = x

Therefore 45(p) = 30(q), or divide both sides by 5 and get 9(p) = 6(q). I know you can divide it further, but these numbers are small enough and it's not worth the time.

Since the whole trip took an hour, (p + q) = 60min, and so, p = 60-q.

Therefore 9(60-q) = 6q or 540-9q = 6q. So 540 = 15q, which makes q = 36. If q = 36, then by (p+q)=60, p (the time she took in the morning) must equal 24.

45 miles per hour, her speed in the morning, times (24/60) hours, her time, makes 18 miles travelled in the morning. If you check, 30 miles per hour times (36/60) hours also makes 18 miles in the evening.
