    And for (B) What operation do you think you'll need to use there if it's 550km for each of h hours?

    (By operation, I mean: +, -, ×, ÷)

    There is nothing to solve. It is merely asking for a representation / an expression.

    unless it told you the area or perimeter, I really can't help you there, darling. Sorry. But I suppose you would just draw what I did?

    What if it was 550 km per hour for 2 hours, how could you find the distance?

    550 x 2

    Right, but it said that it was for h hours. It's using h to represent any number. If h=2 then it would be like you wrote, but since it's just h, do the same thing but with h instead of 2.

    Yes, distance = 550h.
