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.
