Answer 2

Answer:- The average speed of Harvey the wonder hamster is$12\frac{2}{3}\ km/hour$.

Explanation:-

Given: Distance traveled by Harvey $=3\frac{1}{6}\ km=\frac{19}{6}\ km$

Time taken$=\frac{1}{4}\ hour$

$Speed=\frac{Distance}{Time}\\\Rightarrow\ Speed=\frac{\frac{19}{6}}{\frac{1}{4}}\\\\=\frac{19\times4}{6}\\\\=\frac{38}{ 3}\\\\=12\frac{2}{3}\ km/hour$

Therefore, the average speed of Harvey the wonder hamster is$12\frac{2}{3}\ km/hour$.
