Answer :
Final answer:
Nic paddled through a total of 3340 metres of rapids, which is equivalent to 3.34 kilometres. The calculation involved determining the total length of both 540 metre and 860 metre rapids separately before adding them together. Finally, we converted the total from metres to kilometres.
Explanation:
Canoeing Rapids Calculation
In this problem, we will calculate the total length of the rapids Nic paddled through, including both types of rapids he encountered.
a. Calculate the length of the rapids in metres
Nic canoed down three rapids measuring 540 metres each, and two rapids measuring 860 metres each. We can calculate the total length by following these steps:
- Calculate the total length of the three 540 metre rapids:
Total length of 540 metre rapids = 3 540 = 1620 metres
- Calculate the total length of the two 860 metre rapids:
Total length of 860 metre rapids = 2 860 = 1720 metres
- Add both totals to find the overall length:
Overall length of rapids = 1620 + 1720 = 3340 metres
b. Express this distance in kilometres
To convert metres to kilometres, we divide the total number of metres by 1000 (since 1 kilometre = 1000 metres):
Distance in kilometres = 3340 / 1000 = 3.34 kilometres
Thus, Nic paddled through a total of 3340 metres of rapids, which is 3.34 kilometres.
