1	Problem	Sarah is filling up a swimming pool with a hose that delivers water at a rate of 4,500 ml per minute. How many liters of water will be in the pool after 7 hours of continuous filling?
2	Step	Rate of water delivered by the hose	4,500 ml per minute
3	Step	Let’s convert 4,500 ml per minute to liters per minute (since 1 liter = 1,000 ml):	\$ 4,500 ml = (4,500) / (1,000) = 4.5 "liters per minute" \$

Problem

Sarah is filling up a swimming pool with a hose that delivers water at a rate of 4,500 ml per minute. How many liters of water will be in the pool after 7 hours of continuous filling?

Step

Rate of water delivered by the hose

4,500 ml per minute

Step

Let’s convert 4,500 ml per minute to liters per minute (since 1 liter = 1,000 ml):

\$ 4,500 ml = (4,500) / (1,000) = 4.5 "liters per minute" \$

Step

Now, calculate the amount of water delivered in 7 hours:

Number of minutes in 7 hours = \$(7 "hours") \times (60 "minutes per hou"r")\$ = 420 minutes

Step

Total water delivered in 7 hours

\$(4.5 "liters per minute") \times (420 "minutes")\$

Step

Total water delivered

\$4.5 \times 420\$ = 1890 liters

Step

Therefore, after 7 hours of continuous filling at a rate of 4,500 ml per minute, there will be 1890 liters of water in the pool.
