Question

Allen runs 8 miles in 3 hours at a steady pace. How long does it take him to run 3 miles?

Answer 1

We know that she runs 8 miles in 3 hours and we have to find how much time it takes to run 3 miles.
Let time be x and now lets put in the numeric form.
$\frac{8}{3}$ = $\frac{3}{x}$
now cross multiplying each other so we get
8 * x = 3 * 3
8x = 9  { dividing both sides by 8 }
x = 9/8
or
x = 1.125 hrs.
