Answer 1

Given

Distance, d=400 miles

Speed, v=65 miles/hr

To find

The time taken

Explanation

We know speed is given by the ratio of the distance to time taken

Thus,

$\begin{gathered} v=\frac{d}{t} \\ \Rightarrow65=\frac{400}{t} \\ \Rightarrow t=6.15hr \end{gathered}$

Conclusion

The time taken is 6.15 hr
