A​ "bullet" train set a new world record for train speed at 552 kilometers per hour during a manned test run on the Test Line in April 1999. The Test Line is 42.8 kilometers long. How many minutes would a test run on the Test Line last at this​ record-setting spee

Jason and Eddie are traveling from Atlanta to Miami which is a distance of 662 miles. It took them two hours and 45 mins to get to Valdosta Georgia. Then, they made it from Valdosta to Miami in 8 hours and 30 minutes. what would be Jason and Eddie's average speed for this entire trip?

You plan on making a one-hour stop for lunch, and two 10-minute gas/rest stops along the way.  What is your revised travel time in minutes for a one-way trip? According to the trip planner, it takes 3hrs and 4 minutes one way for this trip.

Tom Cogwagee Longboat, of the Six Nations of the Grand River, is one of Ontario's best known distance runners. In 1907, he set a new Boston Marathon record, beating all of the previous decade's champions by almost 5 minutes! If he ran the 39.2 km course in 2 hours, 24 minutes and 24 seconds, what was his speed? HINT: we'll need our units to be metres per second - what do you need to convert in the question? 0.221 m/s O 0.272 m/s O 4.52 m/s O 17.5 m/s

Dennis hiked for about 4 hours and reached the top of the mountain. He traveled 36 meters in total to reach the top. He did not take any breaks and traveled at a steady pace;  how fast was he traveling?

A research group at Dartmouth College has developed a Head Impact Telemetry (HIT) System that can be used to collect data about head accelerations during impacts on the playing field. The researchers observed 249,613 impacts from 423 football players at nine colleges and high schools and collected collision data from participants in other sports. The accelerations during most head impacts (>89%) in helmeted sports caused head accelerations less than a magnitude of 400 m/s2m/s2. However, a total of 11 concussions were diagnosed in players whose impacts caused accelerations between 600 and 1800 m/s2m/s2, with most of the 11 over 1000 m/s2m/s2 Suppose that the magnitude of the head velocity change was 13 m/sm/s. Find time interval for the collision which would produce a possible concussion with an acceleration of 1000 m/s2m/s2?
