Question

Josie walks 3/4 miles in 1/5 hour. what is josie’s speed in miles per hour

Answer 1

Speed = 3.75 miles per hour.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

`Speed = (distance)/(time)`

`S = (d)/(t)`

Given the following data;

Distance, d = 3/4 miles

Time, t = 1/5 hour

Substituting into the equation, we have;

`Speed, S= (3/4)/(1/5)`

`Speed, S = (3)/(4)*5`

`Speed, S = (15)/(4)`

Speed, S = 3.75mph.

Therefore, Josie's speed is 3.75 miles per hour.
