<span>6 km × 1 hour/(b-4 km) = 12 km × (1 hour/(b+4 km)
6/(b-4) hours = 12/(b+4) hours
6(b+4) = 12(b-4)
6b + 24 = 12b - 48
72 = 6b
b = 12

Answer:
You have completed only half in a 1/4 of a day
Step-by-step explanation:
think of it this way
lets say in half a day e.g at 12pm you finish the report
half of 12 is 6
so that would be a 1/4 of the day
100%=24 hours=whole day
50%=12 hours=half a day
25%=6 hours = quarter of a day
25% = 1/4
