Question

Because of road construction in one city, commuters were advised to plan that their Monday morning commute would take $150$% of their usual commuting time. Explain what this means.

Short answer

This means that the commuting time must be increased by half.

Step-by-step solution

Step 1. Given Information

The Monday morning commute would take $150$% of their usual commuting time.

The objective is to explain what does it mean.

Step 2. What is the meaning

The statement means that the commuting time will increase by half.

For example if the previous commuting time was $12$hours then the new commuting time would be

$\begin{array}{rcl}12+\frac{1}{2}\times 12& =& 12+6\\ & =& 18hours\end{array}$

So the new commuting time has been found by increasing the original commuting time by half.
