Al and Bea went jogging together, starting at the same point. Al's velocity can be modeled by va(t)=5e-t and Bea's velocity can be modeled by vb(t)=10e-t. Both are measured in miles/hour.(a)(8 points) After 2 hours, how many miles has Bea run?(a)(b)(8 points) Two hours after they started, how much further along has Bea run than Al? Hint: the difference of their displacements.(b)(c)(6 points) What is the acceleration function for Bea?(c)(d)(8 points) What is the displacement function for Al ?(d)
