Answer:
Average speed, v = 1.66 km/h
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, [tex]d=d_1+d_2+d_3[/tex]
[tex]d=2+0.5+2.5=5\ km[/tex]
Average velocity, [tex]v=\dfrac{5\ km}{3\ h}=1.66\ km/h[/tex]
So, the average speed during the entire journey is 1.66 km/h. Hence, this is the required solution.
