Here's the complete question:
The Nile river is 4160 miles long, you want to spend three weeks traveling the entire length of the river. Estimate the number of miles you should travel each day.
We should note that 7days = 1 week
3 weeks = 3 × 7 = 21 days.
The number of miles that should be travelled each day will be:
= 4160 / 21
= 198 miles
