Practice makes perfect
Let's start by copying the given statement.
7gal/min≈qt/sec
In this exercise, we need to change gallons per minute into quarts per second. Since this will involve multiple conversion factors, let's organize them in a table.
Starting Unit
Converted Unit
1 gallon
4 quarts
1 minute
60 seconds
To perform this conversion, we need to multiply the given value by all of these conversion factors. Remember, we need to arrange these ratios such that every unit we do not want gets canceled out and only the units that we want will remain.
