If I start at a speed of 12mi/h and end at a speed of 32mi/h and I traveled 2 miles, what was my acceleration rate?
:
Find the average speed
Av = %2832%2B12%29%2F2
Av = 44%2F2
Av = 22 mph
:
Find the time it takes to travel 2 mi at 22 mph
t = 2%2F22
t = .0909 * 60 = 5.45 minutes
:
Find the acceleration rate
a = %2832-12%29%2F5.45
a = 20/5.45
a = 3.67 mph/min
