Average Speed of a Vehicle The average speed of a vehicle in miles per hour on a stretch of Route 134 between 6 a.m. and 10 a.m. on a typical weekday is approximated by the expression
where t is measured in hours, with t = 0 corresponding to 6 a.m. Over what interval of time is the average speed of a vehicle less than or equal to 35 mph?

Initially, the solution contains 21 lb of salt. A salt solution with a concentration of 3 lb of salt per gal begins flowing into the tank at the rate of 3 gal per minute. The solution in the tank also begins flowing out at a rate of 3 gal per minute. Let y be the amount of salt present in the tank at time t. (a) Find an expression for the amount of salt in the tank at any time. (b) How much salt is present after 51 minutes? (c) As time increases, what happens to the salt concentration?arrow_forward
