 Motion Practice #1 – average speed, distance, and time For each problem: list given variables with their units, and write out the equation in the form it will be used before substituting the values in. Be sure to box in your final answers with correct units. Roger Bannister was the first person to run the mile in less than 4 min. He accomplished this feat in a time of 3.00 min 59.4 s in 1954. Compute his average speed in both mi/hr and m/s. The 1980 speed record for human-powered vehicles was set on a measured 200 m run by a sleek machine called Vector. Pedaling back-to-back, its two drivers averaged 62.92 mi/hr. This awkward mix of units is the way the data appeared in an article reporting the event. Determine the speed in m/s, and then compute how long the record run lasted. A 600 km cross-country automobile race is won by a team of two drivers, each of whom had the wheel for half the distance of the trip. If one averaged 60 km/hr and the other 20 km/hr, what was their overall average speed? Usain Bolt won the 100m with an average speed of 37.15 km/hr. What was his time for this race in seconds?
