The longest river in the world is the Nile River. It is 4,132 miles long. The longest river in the United States is the Missouri River. It is 2,540 miles long. Which is the best estimate of the difference in the lengths of the Nile and Missouri rivers?

Step-by-step explanation:

We want to solve the difference between the Nile River and the  Missouri River.

Given data

Length of the Nile River= 4,132 miles

Length of the  Missouri River=2,540 miles

A rough estimate or a guess from the  head for the difference will be around

1,600 mile

let us solve and see

difference= 4,132-2,540

difference=1592 miles

hence the difference is 1592 miles

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
