Answer:
54.81 mph
Explanation:
Initial reading on the odometer = 21395 miles
Final reading on the odometer = 22125 miles
Total time the car travelled = 13.5 hours
Distance covered by the car
22125-21395 = 740 miles
As acceleration is not given assume it as constant.
Speed = Distance / time
[tex]\frac{740}{13.5}=54.81\ mph[/tex]
∴ Average speed the car traveled during this trip is 54.81 mph
We have that the average speed the car traveled during this trip
[tex]V=54.07miles/h[/tex]
From the question we are told that
At the start of a trip, the odometer on a car read 21,395
At the end of the trip, 13.5 hours later, the odometer read 22,125
Generally the equation for the speed is mathematically given as
[tex]V=\frac{d}{t}\\\\V=\frac{(22125-21395)}{13.5}\\\\V=54.07miles/h[/tex]
Therefore
The average speed the car traveled during this trip
[tex]V=54.07miles/h[/tex]
