Question

A city bus travels 6 blocks east and 8 blocks north. Each block is 10pm long. If the bus travels this distance i. 15 minute, what is the average speed of the bus(m/s)?​

Answer 1

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

$d_1 = 6 \cdot 100 = 600 m$

- Then, it travels 8 blocks north, so the distance covered is

$d_2 = 8 \cdot 100 = 800 m$

So the total distance covered is

$d=d_1 +d_2 = 600 + 800 = 1400 m$

The average speed is given by

$s=\frac{d}{t}$

where d is the total distance and t the time taken.

The time taken by the bus is

$t = 15 min \cdot 60 = 900 s$

So, the average speed is

$s=\frac{1400}{900}=1.56 m/s$
