(Speedy Snails) INTRODUCTION Mathematics can be used to solve the problem happened in our life such as finding distance or time. Now, we've got a problem here. We want to know following questions below. Let us solve the problem by using mathematical method. There are three snails; slippery, slimy and slidey. They enter a ten-metre race for food. Each snail runs according to the following rules. Slippery : d= 4.4 + 0.55t Slimy : d= 0.3t(t-7) Slidey : d= 0.3t(t-3.4)(t-9) The snails race from a designated starting point toward a designated finish line. The distance, d, is measured in metres, and the time, t, is measured in minutes. QUESTIONS 1. Find the distance of each snail from the start after: (An appropriate window and graph) There are two ways to solve the question 1. Firstly, we can substitute the time into each formula. (a) 0 minutes Slippery : d = 4.4 + 0.55t = 4.4 + 0.55(0) = 4.4 + 0 ...
