Inca roads and runners
Topic What we know Length about 30,000 to 40,000 km of roads (sources give different totals) Travel people and goods moved without wheels or draft animals Chasquis relay runners who took over at stations a few km apart (most chroniclers say about 2.5 km; others give 6 to 9 km); estimates of a day's travel range from up to 300 km to 360–480 km Tambos roadside buildings with supplies and lodging How far apart were the chasqui stations, Pia asks?
- About 2.5 to 9 km, by different accounts
- About 25 to 90 km
- About 30,000 km
- About 300 to 480 km
What did tambos hold, Ren asks?
- Relay runners' horses
- Gold coins
- Wheeled carts
- Supplies and lodging
Why does the chart give a range, 30,000 to 40,000 km, instead of one number, Ari asks?
- The roads change length each day
- 40,000 is the exact length
- Sources give different totals
- The chart could not count
Suppose a message went 300 km each day. How far would it go in 100 days, and how does that compare with the road range, Bo asks?
- 40,000 km exactly: the high end
- 30,000 km: the low end of the range
- 400 km: a short trip
- 3,000 km: far below the range of the roads
Suppose stations were 2.5 km apart. How many handoffs would a message have in 300 km, Esme asks?
- About 120
- About 12
- About 302
- About 750
Is the road system longer than 25,000 km, Jun asks?
- No, under either total
- It can't be known
- Just when the total is 40,000
- Yes, under either total
Why use relay runners instead of one runner, Kira asks?
- One runner is faster over a long distance
- Relays slowed the message
- Fresh runners kept the message fast
- Runners rode wheeled carts
Why build tambos along the roads, Luz asks?
- To store wheels
- To mark the end of the roads
- To stop people traveling
- Travelers needed supplies and rest
