Answer :
The set of calculations could be used to convert her speed to miles per hour is 3.628[tex]miles hr^{-1}[/tex].
There are times when the units used for the measurement do not match the measurement preference and convenience as well as the standards prescribed for certain processes and applications. Converting such units to an extent that it can be understood directly and applied properly is important. To better understand the statement, let us consider the example of a person who is only familiar with the metric system. The person cannot easily figure out the height of a tree measuring 25 feet. Converting 25 feet to metres will help the person better understand the height of the tree. Let us learn unit conversions with the help of a unit conversion table. In this article, we have provided different units of conversion used for the measurement of different parameters.
1m= 3.281 feet
1mile = 5280 feet
Speed = [tex]\frac{1500m}{15.42min}[/tex] = [tex]\frac{1500*3.281 feet}{15.42*\frac{1}{60hr} }[/tex]
Speed= [tex]\frac{1500*3.281}{15.42*\frac{1}{60hr} } *\frac{1miles}{5280}[/tex]
Speed= [tex]\frac{1500*3.281*60}{15.42*5280 } *miles hr^{-1}[/tex]
Speed= 3.628[tex]miles hr^{-1}[/tex]
The set of calculations could be used to convert her speed to miles per hour is 3.628[tex]miles hr^{-1}[/tex].

If a swimmer finished 1500-meter freestyle in 15.42 minutes, her speed is 3.6 miles per hour.
To convert the swimmer's speed to miles per hour, we need to first convert the distance she swam (1500 meters) to miles, and then we need to convert the time it took her to swim that distance (15.42 minutes) to hours.
We can use the following set of calculations to do this:
Convert the distance from meters to miles:
1500 meters × (3.281 ft / 1m) × (1 mile/ 5280 ft) = 0.93 miles
Convert the time from minutes to hours:
15.42 minutes × (1 hour / 60 minutes) = 0.257 hours
Divide the distance by the time to find the speed in miles per hour:
0.93 miles / 0.257 hours = 3.6 miles per hour
This is one set of calculations that can be used to convert the swimmer's speed to miles per hour.
