Your family is driving to Disney which is 1000 miles away. The first day your family drives 600 miles in 10 hours and the second day they drive the remaining distance in 8 hours. What is the average speed of travel for the second day?

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
