A bus travels at an average speed of 60 miles per hour on the highway. Once inside city limits, the bus decreases its speed by 55%

Respuesta :

Answer:

Thus the speed of the bus after it decreased by 55% is now 27 miles per hour.

Step-by-step explanation:

In this solution and based on the information given we assume that the question is:

"What is the speed of the bus after it decreased by 55%?"

We know the original value of the speed is [tex]60\frac{m}{h}[/tex]

We know that the speed decreased by [tex]55[/tex]% of it's original value, where [tex]55[/tex]% is the equivalent of [tex]\frac{55}{100}=0.55[/tex]

To find the new value (lets call it  [tex]s_{new}[/tex]) we have to find the 55% of the original value and then subtract it from the original as follow:

[tex]s_{new}=60-60(0.55)\\s_{new}=60-33\\s_{new}=27\frac{m}{h}[/tex]

Thus the speed of the bus after it decreased by 55% is now 27 miles per hour.
