Question

Ana runs 3/4 mile in 6 minutes, or 1/10 hour. Assuming she runs at a constant rate, what is her speed, in miles per hour?

Answer 1

Her speed would be 7.5 miles per hour

Explanation:

60/6 = 10

3/4 * 10 = 7.5

Answer 2

Her speed in miles per hour is 7.5miles pee hour

Explanation:

Speed is defined as the change in distance of a body or an object with respect to time. Mathematically;

Speed = Distance/Time

Given distance = 3/4miles

Time = 1/10hour

Substituting this data's given in the formula for calculating speed gives;

Speed = {3/4}/{1/10}

Speed = 3/4× 10/1

Speed = 30/4

Speed = 7.5miles/hour
