Question

Distance travelled = rate (or speed) * time.If Deandre drives 203 miles at a constant speed of 58 mph. How long will it take? (Be sure to includeunits.)

Answer 1

Given the formula;

`\begin{gathered} \text{Distance}=\text{Speed}* time \\ D=s* t \end{gathered}`

Then, the time taken is the ratio of the distance and the speed. That is;

`t=(D)/(s)`

But Deandre drives 203 miles at a constant speed of 58mph. Then, the time it took would be;

`\begin{gathered} \text{Where;} \\ d=203\text{miles} \\ s=58\text{mph} \\ t=(203)/(58) \\ t=3.5 \end{gathered}`

Hence, note that the unit of time in the problem is hour. Thus, the time taken to drive 203 miles at a constant speed of 58mph is 3.5hours
