Question 1
Barbara is traveling east through Texas on I-30 at a speed of 76 MPH. The posted limit is 75 MPH. There are two trucks ahead of her, both of which are traveling at a slower rate of speed than Barbara. Barbara pulls into the left-hand lane to pass the slower moving trucks. At what point will the faster of the two trucks pull into the left-hand lane?
A) After Barbara has safely passed them and moved back into the right-hand lane.
B) Just in time for Barbara to have to hit her brakes and reduce her speed by at least 10 MPH.
C) This doesn't happen, Truck drivers are professional and courteous.
Question 2
Barbara is traveling north through Arkansas on I-40 at a speed of 71 MPH. The posted limit is 70 MPH. There are several trucks ahead of her, all of which are traveling at a slower rate of speed than Barbara. Barbara pulls into the left-hand lane to pass the slower moving trucks. At the same time, the faster of the slower moving trucks pulls into the left-hand lane in front of Barbara causing her to hit her brakes and reduce her speed by 10 MPH. How long will it take for the truck to go back into the right-hand lane so that Barbara can resume the speed of 71 MPH?
A) Two minutes.
B) Between three and 10 minutes, depending on the number and speed of the trucks in the right-hand lane.
C) This doesn't happen, Truck drivers are professional and courteous.
Question 3
How many times does a truck need to pull out in front of Barbara to add an additional two hours to a 17 hour trip? (Remember, that speed is reduced by at least 10 MPH every time it happens.)
A) Way too many.
B) 40 Times
C) It doesn't add anything to the trip time. The additional trip time was caused by the 55 MPH limit imposed by the construction zone otherwise known as Kentucky.
Let me know if you need the answer key.
