Question

Estimate the time it would take you to drive 278 miles at38 miles per hour. Round to the nearest hour

Answer 1

Speed formula:

`s=(d)/(t)`

d is the distance

t is the time

As you need to find a time having the distance and speed, solve the equation above for t:

`\begin{gathered} t\cdot s=d \\ t=(d)/(s) \end{gathered}`

Use the given data to find the time:

`\begin{gathered} t=(278mi)/(38mi/h) \\ \\ t=7.31h \\ \\ t=7h \end{gathered}`

Then, it would take you 7 hours to drive 278 mi at 38mi/h
