There and Back Julian biked a 24 km trip to Guelph. On his way there, his average speed was 12 km/h. On his way home, he stopped

Umnica [9.8K]

Time taken by Julian to complete 24 km trip to Guelph at 12 km/h =

$\frac{24}{12}=2$ hours

Time taken by Julian for return trip at 8 km/h = $\frac{24}{8}=3$ hours

As given, the total distance is 24 + 24 = 48 km.

And the total time is 2 + 3 = 5 hrs.

Hence, the average speed for the entire trip is = $\frac{48}{5}= 9.6$

The answer is 9.6 km/hour.
