1. A car travels 40 miles west then goes 30 miles north. How far is the car from its starting point?

10 miles in since they turned around, but if your adding then its 70 miles

Iwould think that the correct answer is 8.1

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
