The average speed is 90.7 m/s or 203.3 mi/h
Explanation:
The average speed of an object is given by:
[tex]speed = \frac{d}{t}[/tex]
where
d is the distance covered
t is the time taken
For the car in this problem:
d = 0.25 miles is the distance covered
t = 4.437 s is the time taken
Let's convert distance and time in all the units required:
1 mile = 1609 m, so
[tex]d = (0.25)(1609)=402.3 m[/tex]
1 hour = 3600 s, so
[tex]t = \frac{4.437}{3600}=0.00123 h[/tex]
So, the average speed in m/s is:
[tex]speed = \frac{402.3 m}{4.437 s}=90.7 m/s[/tex]
And the average speed in mi/h is:
[tex]speed = \frac{0.25 mi}{0.00123 h}=203.3 mi/h[/tex]
