Question

at the start of the trip the odometer reds 53,307. at the end it reads 55,100 how long was the trip in miles?

Answer 1

In the very beginning of the trip since it reads 53,307 miles and and in the end it reads 55,100 miles, you would have to subtract 53,307 miles from 55,100 miles. 
$55,100 - 53,307 = 1,793$ miles
