(8) In this problem time is in hours, and distance is in kilometers (km), and speed is in kilometers per hour (kph). There is a road from Paris to Mongins (on the French Riviera) that is 1000 km long. Pierre drives along this road at constant speed ' starting from Paris at 9am. Mimi starts at 10am from Mougina driving in the opposite direction along this road going towards Paris. Mimi drives at constant speed M kph. After driving for 2 hours, Mimi stops for one hour to have a croissant and expresso. She resumes her journey and speeds up by 20 kph for the rest of the journey. Mimi meets Pierre at 4pm. For (a) and (b) the answer is an equation that can be arranged into the form rM + yl = 2 For example 3M +7/ - 16. In this case a = 3 and y - 7 and = = 16. (a) The equation that expresses the information above has. (b) At 1 lam the combined distance Mimi and Pierre have travelled is 230 jan. The equation that expresses this has: (c) What is the initial speed of Mimi M kphi five the answer as a (decimal) number (d) How many kilometers from Mougins are they when they meet
