Question

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

Answer 1

Answer:

Speed = 3.75 miles per hour.

Step-by-step 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;

$Speed = \frac{distance}{time}$

$S = \frac{d}{t}$

Given the following data;

Distance, d = 3/4 miles

Time, t = 1/5 hour

Substituting into the equation, we have;

$Speed, S= \frac{3/4}{1/5}$

$Speed, S = \frac{3}{4}*5$

$Speed, S = \frac{15}{4}$

Speed, S = 3.75mph.

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