If John mows 40% of the lawn in 20 minutes, we can set up a proportion to find out how long it would take him to mow 100% of the lawn.
Let \( x \) be the total time to mow the whole lawn. Since 40% corresponds to 20 minutes, we can express this as:
\[
\frac{40}{100} = \frac{20}{x}
\]
Cross-multiplying gives us:
\[
40x = 2000
\]
Now, solve for \( x \):
\[
x = \frac{2000}{40} = 50
\]
So, it would take John a total of **50 minutes** to mow the entire lawn.
