a dog can run as fast as 39.35 miles per hour.without calculating,would about 12,14,or 16 be a reasonable answer for the number of miles a dog could run at this rate in 0.4 hour?Explain your reasoning.
0.4 hour is a little less than half
39.35 mph is almost 40 mph
Take it from there.
16
To determine whether 12, 14, or 16 is a reasonable answer for the number of miles a dog could run at a speed of 39.35 miles per hour in 0.4 hours, we can use estimation and reasoning.
First, let's estimate the distance traveled by the dog in 0.4 hours. We can do this by multiplying the speed (39.35 miles per hour) by the time (0.4 hours):
Distance = Speed * Time
Distance ≈ 39.35 mph * 0.4 h
Now, let's estimate the value of this expression:
39.35 mph * 0.4 h ≈ 16
Therefore, 16 miles is the estimated distance that a dog could run at a speed of 39.35 miles per hour in 0.4 hours.
Given that our estimation suggests it would be around 16 miles, we can conclude that of the options provided, 16 would be a reasonable answer.
