Question

Using the formula r = d/t, where d is the distance in miles, r is the rate, and t is the time in hours, at which rate must you travel to cover 185 miles in 2.5 hours?

Answer 1

The formula is:

`r=(d)/(t)`

r is the rate

d is the distance in miles

t is the time in hours

From the question:

d = 185 miles

t = 2.5 hours

r = ?

Let us substitute d and t in the formula above to find r

`\begin{gathered} r=(185)/(2.5) \\ r=74\text{ miles/h} \end{gathered}`

The rate is 74 miles/hour
