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.
so if we are going to calculate the length for each day, we need to multiply the number of weeks by the amount fo days in each week (7) 3*7= 21 days to fidn the distance you should travel per day, divide the total distance by the amount of days 4160 divided by 21 equals about 198.1 miles per day
