Arrival-Time Drill

Before tapping "directions" on your phone, estimate the trip yourself. Look up the distance and divide by a benchmark speed: 60 mph on highways, 25 mph in a city, 12 mph on a bike, 3 mph walking.

A 15-mile city drive is 15 ÷ 25 = 36 minutes. For a two-leg trip, compute each leg on its own: 20 highway miles (20 min) plus 5 city miles (12 min) totals 32 minutes. Run the drill on a few real trips and the estimates start to feel automatic.
