Question

88 feet/second = 60 miles/hour. How many feet per second is 1 mile? (Hint: divide both side of the equation by the same amount.)

Answer 1

1 mile/hour is equivalent to 1.47 feet/seconds

Explanation:

Given

`88 ft/s= 60 miles/hr`

Required

Determine the equivalent of 1 mile/hour

`88\ ft/s= 60\ miles/hr`

Express 60 as 60 * 1

`88\ ft/s= 60 * 1\ mile/hr`

Divide both sides by 60

`(88\ ft/s)/(60)= (60 * 1\ mile/hr)/(60)`

`(88\ ft/s)/(60)= 1\ mile/hr`

Reorder

`1\ mile/hr = (88\ ft/s)/(60)`

Divide 88 by 60

`1\ mile/hr = 1.46666666667\ ft/s`

Approximate to 3 significant figures

`1\ mile/hr = 1.47\ ft/s`

Hence;

1 mile/hour is equivalent to 1.47 feet/seconds
