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.
