Can someone show me the methods used in the question?

(C) Is there a time t, for 0 S t S 4, at which Brandon's acceleration is equal to 2.5 miles per hour per hour? Justify your answer. (d) Is there a time t, for 0 S t S 2, at which Brandon's velocity is equal to Chloe's velocity? Justify your answer. Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers & for which f () is a real number. t (hours) 0 1 2 3 4 B(t) (miles per hour) 1 8 1.5 -5 11 Brandon and Chloe ride their bikes for 4 hours along a flat, straight road. Brandon's velocity, in miles per hour, at time t hours is given by a differentiable function B for 0
