Help, please! 1. The first problem states that we need to find the speed of the kayak using the previous speeds of the other boats. The steamboat's speed is 20 knots and the tall ship's speed is 10 knots. The steamboat's speed is 4 less than 8 times the speed of the kayak. The tall ship's speed is 1 more than 3 times the speed of the kayak. Write and solve an equation for the speed of the kayak. Show your work. 2. The length of the trip to the island is 40 nautical miles less than 20 times the distance to the reef. distance to the island = 5s (s = speed of boat) It is 2:00 p.m. now, and your boat leaves the island at 7:30 p.m Will you be able to kayak to the reef and back by then? - If so, how long will you have to spend at the reef? - If not, how late will you be for the return trip. Explain how you plan to solve the problem. Then solve the problem, showing all work. (explanation of the plan, deciding if you'll make it back on time, and determining either how long you can spend at the reef or how late you'll be.
