Hi there! The answer is 15 minutes.
Walking 4 miles per hour means that it takes you 60 minutes to walk 4 miles. To find the time it takes you to walk 1 mile, we must divide both sides by 4.
4 miles equals 60 minutes.
1 mile equals 60 / 4 = 15 minutes.
The answer is 15 minutes.
Functions can be represented using equations, graphs and tables.
The function is given as:

When l = 1, we have:


When l = 2, we have:


When l = 3, we have:


When l = 4, we have:


Represent the above results as a table, we have:
<u>l a(l)</u>
1 0.5
2 2.0
3 4.5
4 8.0
