If a car travels 180 miles in 4 hours, how many miles would it go in 6?
worty [1.4K]

Answer:

270

Step-by-step explanation:

First, to find how far the car will go in one hour, you do 180 divided by 4. We already know that the car drives at a constant rate. If you do 180 divided by 4, you get 45. Then you multiply 45 by the amount of hours (6) to get 270
