2. The hull of a boat is cracked after hitting a rock and water starts to leak in. Starting at timc t = 0 hours, water enters the boat at the rate r(t), measured in litres per hour. The following table contains some values of r(t): 1 0 0 .5 3 1.0 7 1.5 2.0 2.5 3.0 3.5 4.0 10 | 13 | 17 | 19 | 21 | 22 r(t) 0 The integral r(t) dt cquals the amount of water to enter the boat in the first 4 hours. Which of the following is the approximation for this integral obtained for by using the trapezoid rule with n = 4 (A) 40 (B) 45 (D) 55 ANSWER:
