Answer: C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
Explanation:
The speed of each car is defined as:
[tex]v=\frac{d}{t}[/tex]
where d is the distance traveled by the car and t is the time taken.
For the yellow car, d=400 mi and t=8 h, so its speed is
[tex]v=\frac{400 mi}{8 h}=50 mph[/tex]
For the green car, d=400 mi and t=10 h, so its speed is
[tex]v=\frac{400 mi}{10 h}=40 mph[/tex]
So, the correct choice is
C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
Answer:
C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
Explanation:
The speed is defined as ratio of distance covered with time:
[tex]v = \frac{distance}{time}[/tex]
[tex]v = \frac{d}{t}[/tex]
here
d = the distance traveled by the car and
t = the time taken.
For the yellow car,
d=400 mi
t=8 hours
so speed of yellow car is given as
[tex]v_{yellow} = \frac{400}{8} = 50 mph[/tex]
For the green car,
d=400 mi
t=10 hours,
so speed of green car is
[tex]v_{green} = \frac{400}{10} = 40 mph[/tex]
So, the correct choice is
C)The yellow car was faster. Yellow traveled at a speed of 50 mph while green was traveling at an average of 40 mph.
