Question

Elsa went for a drive in her new car. She took 9 hours to drive 460.8 miles. What was her speedmiles per hour

Answer 1

Given:

`\begin{gathered} \text{time, t = 9hours} \\ dis\tan ce,\text{ d=460.8miles} \end{gathered}`

The formula for calculating speed is given by;

`\text{speed}=\frac{distance}{\text{time}}`

Substituting the given data into the formula,

`\begin{gathered} \text{speed}=\frac{distance}{\text{time}} \\ \text{speed}=(460.8)/(9) \\ \text{speed}=51.2\text{miles per hour} \end{gathered}`

Therefore, Elsa's speed was 51.2 miles per hour
