Answer:
1.56 m/s
Explanation:
The lenght of each block is 100 m. This means that the bus travels the following distances:
- At the beginning, 6 blocks east, so the distance covered is
[tex]d_1 = 6 \cdot 100 = 600 m[/tex]
- Then, it travels 8 blocks north, so the distance covered is
[tex]d_2 = 8 \cdot 100 = 800 m[/tex]
So the total distance covered is
[tex]d=d_1 +d_2 = 600 + 800 = 1400 m[/tex]
The average speed is given by
[tex]s=\frac{d}{t}[/tex]
where d is the total distance and t the time taken.
The time taken by the bus is
[tex]t = 15 min \cdot 60 = 900 s[/tex]
So, the average speed is
[tex]s=\frac{1400}{900}=1.56 m/s[/tex]
