Can someone help show me how I would plot this in Excel?

Example 4.2 The travel time on a stretch of a highway lane connecting two activity centers has been observed to follow the equation representing the service function: t= 15 + 0.0211 where t and v are measured in minutes and vehicles per hour, respectively. The demand function for travel connecting the two activity centers is v = 4000 120t (a) Sketch these two equations and determine the equilibrium time and speed of travel. (b) If the length of the highway lane is 20 mi, what is the average speed of vehicles traversing this length? Solution Solving the two equations: t = 15 + 0.02v v = 4000 120t results in the following values for v and t at equilibrium (as shown in gge E42): v = 647 veh/hr t = 27.94 min 20X60 Speed = 27.94 = 42.95 mph Time, t (min) t: 15 + 0.021! (647, 27.94) v = 4000 - 120t 2000 4000 v (vehicles/hr) Figure E42 Static equilibrium of demand and supply
