    Yep! 81/2.5 gives you the answer.

    either these laps were really short, or this cat is fast

    "per" means "divided by" time per lap time divided by lap

    we want the time for 1 lap, so we need to turn that `2.5` into `1` we do this by dividing both parts by `2.5` |dw:1444098863157:dw|

    2.5 divided by itself is 1 |dw:1444098893958:dw|

    so you just need to compute 81/2.5 to get your answer
