Answer 1

I can’t solve this as written because the problem statement has blanked-out numbers (e.g. "kilometers in ___ of a minute"). Could you paste the full text with the actual numbers, or tell me the two distances and the two time amounts?

If you want the general method so you can fill it in yourself:
- Unit rate = (kilometers) ÷ (minutes). If time is a fraction, divide by that fraction (or multiply by its reciprocal).
- Then subtract the two unit rates to get the difference and decide whether it’s faster or slower.

Send the missing numbers and I’ll compute the exact answers and pick the choices.
