Suppose three competing airlines each schedule their own flight to Waco which arrives there between 2:00 and 3:00 pm according to a continuous uniform distribution. All three flights are mutually independent. (a) If Ralph shows up at the airport at 2:00 and decides he will watch all three arrivals, what is the expected time that he observes the third and last arrival?

First convert the distance to miles 9.5 × 10^12 km x 0.62 miles/km = (0.62 × 9.5) x 10^12 miles = 5.9 × 10^12 miles But we want to triple that, because it is 3 light years (not just 1): 3 x 5.9 × 10^12 miles ≈ 18 × 10^12 miles ≈ 1.8 × 10^13 miles Next divide by the speed to get the time (in hours). t = 1.8 × 10^13 miles / 17000 miles/hour Let s convert the speed to scientific notation: t = 1.8 × 10^13 / 1.7 x 10^4 t = (1.8 / 1.7) × (10^13 / 10^4) -- when dividing
