Question

A line to vote is moving at a rate of 5 feet every 20 minutes. At this rate, how long has a voter been in line for if they moved 30 feet?

Answer 1

In order to solve for time, we will solve as follows:

We multiply the movement in the time we want to know (30 ft) times the time it takes to move 5 ft (20 min) and divide it by the 5 ft, that is:

`t=(30\cdot20)/(5)\Rightarrow t=120`

From this, we know it took the voter 120 minutes to move 30 ft.
