Question

Calculate the distance covered by a bus safe to travel at a speed of 70 KM H and it travels from 2 hour 30 minute

Answer 1

Answer:

175 km

Explanation:

As per the provided information in the given question, we have :

• Speed (v) = 70 km/h
• Time taken (t) = 2 hours 30 minutes

We are asked to calculate the distance covered in that time.

Before commencing the steps, let convert time taken in hours.

$\longmapsto\rm{t = 2\; hr \; 30 \; min}$

$\longmapsto\rm{t = 2\; hr + 30 \; min}$

$\longmapsto\rm{t = \Bigg (2 + \dfrac{30}{60} \Bigg ) \; h}$

$\longmapsto\rm{t = \Bigg (2 + \dfrac{1}{2} \Bigg ) \; h}$

$\longmapsto\rm{t = \Bigg (\dfrac{4 + 1}{2} \Bigg ) \; h}$

$\longmapsto\rm{t = \dfrac{5}{2} \; h}$

Therefore, time taken 5/2 hours. Now, finding distance covered. As we know that,

$\longmapsto\bf { Distance = Speed \times Time}$

Substituting values, we get :

$\longmapsto\rm { Distance = \Bigg ( 70 \times \dfrac{5}{2} \Bigg ) \; km}$

$\longmapsto\rm { Distance = \Bigg ( 35 \times 5 \Bigg ) \; km}$

$\longmapsto\bf { Distance = 175 \; km}$

∴ Distance covered is 175 km.

More Information :

• Distance covered is total length of the path covered by the body.
• It is scalar quantity.
• Its SI unit is metre (m).
• It is denoted by s.
• Distance = Speed × Time
