Problem:
- 50 miles/hour = ? feet/second
Conversions Factors:
- 1 mile = 1760 yards
- 1 yard = 3 feet
- 1 minute = 60 seconds
- 1 hour = 60 minutes
The first step I would do is combine the conversion factors to go from unit you are given to unit you want. Remember, units can cancel just like numbers and variables can, when using a faction.
1 mile = 1760 yards and 1 yard = 3 feet
( 1 mile / 1760 yards ) x ( 1 yard / 3 feet ) = ( 1 mile / 5280 feet )
This can be rewritten as: 1 mile = 5280 feet
( 60 seconds / 1 minute ) x ( 60 minute / 1 hour ) = ( 3600 seconds / 1 hour )
This can be written as: 1 hour = 3600 seconds
Now if you have 50 miles/hour.
( 50 miles / hour ) x (1 hour / 3600 seconds ) = 50/3600 miles/second
( 50/3600 miles / second ) x ( 5280 feet / 1 mile ) = 264000/3600 feet/second
Simplify the fraction:
264000/3600 feet/second = 2640/36 ft/s ~= 73.33 ft/s
The answer is 73.33 ft/s. Try working this out on your own. When you can see the fractions written normally, versus the way they have to entered on this site, it can be a little confusing to follow. When you see them on paper, it begins to make sense why they are cancelling out.
