The diagram shows a pool that is 100m wide. A person swims 4 lengths of the pool from one edge to the other. It takes the swimmer 1 hour. A) what is the swimmers average speed? B) what is the swimmer average velocity? (Include magnitude and direction). Please help

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.
