Q:
# Natalie walked 3/5 mile in 1/2 hour how fast did she walk in miles per hour

Accepted Solution

A:

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.
