Answer:
0.45 miles
Explanation:
since, car will be running on the edge of track, distance covered in one lap by car will be equal to circumference of track.\
we will use value of pi as 22/7
Circumference for any circular shape is given by
Hence, in one lap distance will be covered
in 7 laps distance will be covered.
but is given that 7 laps should be equal to 10 miles
so 10 miles will be equal to
Thus, diameter of track will be 0.45 miles to meet the requirement.
Answer:
a=∆v/∆t
Explanation:
The definition of Acceleration is the change in velocity in a given time. So this means you first calculate ∆v (Change in velocity), and you calculate ∆t which is the time taken to apply that change in velocity. Then you find a= ∆v/∆t. This gives us the equation of Acceleration.
