Question

Lori ran 2 miles in hours. If she ran the entire distance at the same rate, how long

did it take her to run 1 mile?

Answer 1

Half

Explanation:

I think you're missing the number of hours in the question: "Lori ran 2 miles in ? hours"

Anyways:

Lori's speed is distance/time: v = 2 miles / ? hours

Calculate time from speed (time = distance / speed): t = 1 mile / (2 miles / ? hours)

To divide with a partial you can multiply with reciprocal, thus: t = 1 mile x (? / 2 miles)

Simplified: t = (1 / 2) x ? hours

And it makes sense: with the same speed, half the distance takes half the time :)
