Answer please
Need an image file of solutions please, as typed text does not show symbols such as brackets and make solutions confusing.
A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race. Preview Solve f(t) = 0 and describe what your solution represents. t = Preview…
2. With the closure of restaurants during the Covid-19 Pandemic, William and Luxman decided to take advantage of the Uber Eats App by ordering from Pizza Hut. The Uber driver drove a distance of 2x km in 3 hours for Luxman's delivery. For William's order, the driver drove a distance of x + 100 km in 2 hours. a) Write a simplified expression for the difference between the first speed and the second speed. [Hint: Use the equation speed- distance/time] b) Determine the values of x for which the speed was greater for the second trip. c) Are there any restrictions in this context? Explain why.
