In anticipation of a long 7° upgrade, a bus driver accelerates at a constant rate of 3.8 ft/s2 while still on a level section of the highway. Knowing that the speed of the bus is 62 mi/h as it begins to climb the grade and that the driver does not change the setting of his throttle or shift gears, determine the distance traveled by the bus up the grade when its speed has decreased to 50 mi/h. (Round the final answer to three decimal places.) The distance travelled by the bus up the grade is
