- In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of 183.58 mi/h. The one-way course was 5.00 mi long. Acceleration rates are often described by the time it takes to reach 60.0 mi/h from rest. If this time was 4.00 s, and BL11t accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?13. Find the time (Seconds)needed for a car to go from 25m/s to 55 m//s with an acceleration of 1.4 m/s^2? 12. You are driving home from at 85.0 km/h for 130. km, then you slowed down to 70.0 km/h.
