A motorist on a road trip drives a car at different constant speeds over several legs of the trip. He drives for 20.0 min at 60.0 km/h, 5.0 min at 55.0 km/h, and 40.0 min at 60.0 km/h and spends 35.0 min eating lunch and buying gas. (a) What is the total distance traveled over the entire trip (in km)? km (b) What is the average speed for the entire trip (in km/h)? km/h
Example. Suppose the number of customers per hour arriving at a shop follows a Poisson process with mean 30. That is, if a minute is our unit, then \( \lambda = 1/2 \). What is the probability that the shopkeeper will wait more than 5 minutes before both of the first two customers arrive?
