Question

Determine the distance covered by a car traveling 68 mi/h for eachunit and time given. Round answers to the nearest unit. a. miles in one hourb.feet in one hourc.feet in one minuted.feet in one second

Answer 1

Distance is calculated as

`Distance=speed* time`

a.) miles in one hour

Here the speed is given as 68 miles/hr.

The distance in 1 hour becomes

`\begin{gathered} distance=speed* time \\ distance=68*1=68miles\text{ } \end{gathered}`

Hence the answer is 68 miles

b.) Feet in one hour

We have to found the distance in one hour in miles as 68 miles.

So we convert the miles to feet, we have

`\begin{gathered} 1mile=5280feet \\ 68miles=5280*68=359,040feet \end{gathered}`

Hence the answer is 359,040 feet

c.) Feet in one minute

To do this, we divide the distance gotten in feet in one hour by 60. Since 60 minutes make an hour, so we have

`\begin{gathered} (359,040)/(60) \\ =5,984\text{ feet} \end{gathered}`

Hence the answer is 5,984 feet in one minute

d.) Feet in one second

To do this, we divide the distance gotten in feet in one minute by 60. Since 60 seconds make a minute, so we have

`\begin{gathered} (5,984)/(60) \\ =99.733\text{ feet} \end{gathered}`

Hence the answer is 99.73 feet in one second
