The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. at this rate, how many seconds would it take to swim 0.8500.850 miles (1 mi = 1609 m)?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
