Guesstimates
Weekday ferry usage in Mumbai
Estimate boardings per month and explain the boundary, assumptions and range.
Start with 34 weekday sailings per day and 22 operating days. Estimate boardings per 100 sailings before revealing the model.

Multiply the two base factors by the rate divided by 100. All figures below are simulated teaching assumptions.
- Low · 34 × 22 × 5,800 ÷ 100 ≈ 43,384 boardings per month
- Base · 34 × 22 × 8,400 ÷ 100 ≈ 62,832 boardings per month
- High · 34 × 22 × 10,700 ÷ 100 ≈ 80,036 boardings per month
Cross-check · Check seats per sailing and compare peak sailings separately from quieter departures.
