Problem 1. The function f(t) refers to the velocity of a tortoise (in km/hour) at time t (in hours since 12 PM). Positive values of the function refer to eastern movement. t) is given in the graph below. m) 1 100 0 10 Part (a). Compute the value f = t) dt Part (b). Interpret the f in context of the situation. Problem 2. Let f(t) : (t i 2)et2'4t refer to the velocity of a hare (in km/hour) at time t (in hours since 12 PM). Positive values of the function refer to eastern movement. 4 Part (a). Compute the value f (t 2).?2'4t dt. Round your answer to two decimals. 71 Part (b). Interpret the value in part (a) in context of the situation
