Answer:
She will save 23.574 minutes
Step-by-step explanation:
We have given that when she walks to school from her apartment which is 1.1 miles away from her apartment speed is 2 miles per hour
So distance d = 1.1 miles
And speed = 2 miles per hour
We know that [tex]time=\frac{distance}{speed}=\frac{1.1}{2}=0.55hour[/tex]
It is also given that when she ride a bike her speed is 7 miles per hour
So [tex]time=\frac{distance}{speed}=\frac{1.1}{7}=0.1571hour[/tex]
So time saving = 0.55 - 0.1571 = 0.3929 hour
We know that 1 hour = 60 minutes
So time saving [tex]=0.3929\times 60=23.574minutes[/tex]
Victoria saves getting to class each morning if she were to ride the bike in 23.52 minutes.
Given
Victoria currently walks to school from her apartment, which is 1.1 miles away from her first class.
She typically walks at a speed of 2 miles per hour.
She is considering buying a used bicycle from Deseret Industries to ride to campus.
Victoria assumes that if she were riding a bike, she could go about 7 miles per hour.
What formula is used to find the time?
The formula is used to find the value of time is;
[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]
If she goes to school from the apartment by walking then she will take time is;
[tex]\rm Time = \dfrac{Distance}{Speed}\\\\Time = \dfrac{1.1}{2}\\\\Time = 0.55 \ hours[/tex]
If she goes to school from the apartment by bicycle then she will take time is;
[tex]\rm Time = \dfrac{1.1}{7}\\\\Time =0.15 \ hour[/tex]
Therefore,
The time in minutes could Victoria save getting to class each morning if she were to ride the bike is;
[tex]\rm = 0.55 - 0.15\\\\= 0.39 \ hours\\\\\rm 1 \ hour = 60 \ minutes\\\\= 0.39 \times 60\\\\=23.57 \ minutes[/tex]
Hence, Victoria saves getting to class each morning if she were to ride the bike in 23.52 minutes.
