Our job here is to convert the given info to the rate (speed) as a unit measurement.  In other words, we need to calculate how fast Natalie walks in 1 hour.

To do this, divide the distance by the elapsed time:

3/5 mile
------------
1/2 hour

This becomes

3
--
5
==   miles/hour
1
--
2

Invert the divisor (1/2) and multiply:

3      2       6
-- * ---  = -----
5      1       5

The correct answer must include units of measurement.  It is

(6/5) mph.

The speed of Natalie in miles per hour is 1.2 mph.

The given parameters;

  • distance covered by Natalie, d = 3/5 mile
  • time of motion of Natalie, t = 1/2 hour

The speed of Natalie in miles per hour is obtained by dividing the distance covered by Natalie by the time of motion.

The value of this speed is  calculated as;

[tex]speed = \frac{distance }{time} \\\\speed = \frac{3/5}{1/2} = \frac{3\times 2}{5} = \frac{6}{5} = 1.2 \ mph[/tex]

Thus, the speed of Natalie in miles per hour is 1.2 mph.
