From the information given, in order to find who hikes faster, we need to determine the speed of John and Sara. The person with the greater speed hikes faster.

$\text{ Sp}eed\text{ = }\frac{\text{ Total Distance travelled}}{\text{Time}}$

John's speed is determined by:

$\text{ Sp}eed\text{ = }\frac{20\operatorname{km}}{5\text{hrs}}=(4km)/(hr)$

Sara's speed is determined by:

$S\text{peed =}\frac{25\operatorname{km}}{5}=\frac{5\operatorname{km}}{hr}$

Since Sara's speed is greater than John's speed

Therefore, Sara hikes faster than John
