It uses distance equals speed over time, estimates 15.12 mph as 15 mph for a 3069.25 mile distance, giving about 2 hours a day and then calculates 25 training days, noting that increasing average speed to 16.27 reduces the number of days. It then solves additional bonus share, swim pool with taps, pen pack ratios, and several fraction, standard form, and decimal multiplication estimation problems, including a cost estimate for 513 km driving and its overestimate or underestimate.
