The scenario is speed
Travel at
100% = get there in 20 min
150% = 15 min
200% = 10 min
250% = 5 min
300% = 0 min
This is alien to me. Logic dictates that 50% should be half, so 150% should = 10, but maybe this isn't working because 150% is more.
I get this scenario, and why it works
100% = 20
75% = 15
50% = 10
