You are traveling at a speed of 42 miles in .75 hr and slow to a speed of 42 miles in 1.25 hr. What is your rate of declaration?
To find the rate of deceleration, we need to calculate the difference in speed over the given time interval.
First, we need to determine the initial speed. The initial speed is given as 42 miles in 0.75 hours.
Rate = Distance / Time
Initial speed = 42 miles / 0.75 hours
Next, we need to determine the final speed. The final speed is given as 42 miles in 1.25 hours.
Final speed = 42 miles / 1.25 hours
To find the rate of deceleration, we subtract the final speed from the initial speed and divide by the time interval.
Rate of deceleration = (Initial speed - Final speed) / Time
Let's plug in the values:
Rate of deceleration = (42 miles / 0.75 hours - 42 miles / 1.25 hours) / (1.25 hours - 0.75 hours)
Simplifying the expression:
Rate of deceleration = (56 miles/hour - 33.6 miles/hour) / 0.5 hours
Rate of deceleration = 22.4 miles/hour / 0.5 hours
Rate of deceleration = 44.8 miles/hour
Therefore, your rate of deceleration is 44.8 miles/hour.
