Question

Once cubic meter of concrete weighs 5000 pounds. Find the weight of the section. Find the integral integral (z + 1) Squareroot 3z + 2dz A state patrol officer saw a car start from rest at a highway on-ramp. She radioed ahead to a patrol officer 30 miles along the highway. When the car reached the location of the second officer 28 minutes later, it was clocked going 60 mi/hr. The driver of the car was given a ticket for exceeding the 60-mph speed limit. Why can the second officer conclude that the driver exceeded the speed limit between the on-ramp and the second officer's position?

Explanation / Answer

Distance= speed*time
30miles= speed*(28 mins)
Now, 28 mins=(28/60) hrs.
So, speed= (30/(28/60))=30*60/28 = 64.285 mi/hr. So speed must have been greater than 60 miles in between the travel.
