I think there's an issue with the running -themed problems.

It say's "William sprinted first and ran 200 meters in 84.75 seconds. When it was Umaima's turn, she sped off and completed the run in 55.31 seconds. How much faster was Umaima than William?"

William 84.75 seconds
Umaima: 55.31 seconds

The last of these I tried showed that the correct answer value to be positive. So Umaima isn't "minus faster", the names are in wrong order.

Double checked and hints didn't say anything.
