Answer:

Average speed, v = 1.66 km/h

Step-by-step explanation:

It is given that, Ian walks 2 km to his best friend’s house, then walks 0.5 km to the library. He then makes a 2.5 km walk home.

Total time taken in the entire walk, t = 3 hours

We need to find the average speed of the Ian during his journey.

Total distance covered is,
d=d_1+d_2+d_3


d=2+0.5+2.5=5\ km

Average velocity,
v=(5\ km)/(3\ h)=1.66\ km/h

So, the average speed during the entire journey is 1.66 km/h. Hence, this is the required solution.
