Question 13 A bar-tailed godwit holds the record for the longest recorded non-stop flight. It travelled 13,560 km from Alaska to Australia without stopping. Its journey started on 13 October 2022 and continued for about 11 days. Find out the approximate distance it covered every day. Find out the approximate distance it covered every hour. Given Total distance travelled = 13,560 km Duration of the trip = about 11 days Approximate distance covered every day To find out how far it travelled each day, we divide the total distance by the number of days: Distance per day = (𝑇𝑜𝑡𝑎𝑙 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒)/(𝑁𝑖𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑑𝑎𝑦𝑠) = 13,560 km / 11 days ≈ 1232.73 km/day So, the bar-tailed godwit covered approximately 1233 km every day. Approximate distance covered every hour Now that we know the daily distance, We can find the hourly distance by dividing daily distance by the number of hours in a day (i.e. 24 hours) Distance per hour = (𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝑝𝑒𝑟 𝑑𝑎𝑦)/(24 ℎ𝑜𝑢𝑟𝑠) = (1232.73 𝑘𝑚)/(24 ℎ𝑜𝑢𝑟𝑠) ≈ 51.36 km/hour So, the bar-tailed godwit covered approximately 51.4 km every hour. So, the bar-tailed godwit covered approximately 51.4 km every hour.
