Thanks if you answer :)

Respuesta :

She can bike 25 kilometers in one hour.

Step-by-step explanation:

Given,

Distance by walk in 0.5 hours = 5 kilometers

Distance by bike in 0.8 hours = 20 kilometers

Distance in 1 hour = [tex]\frac{1}{0.8}*20\\[/tex]

[tex]Distance\ in\ one\ hour=\frac{20}{0.8}\\Distance\ in\ one\ hour= 25\ km[/tex]

She can bike 25 kilometers in one hour.
