Question

A truck moving on East-West highway covers 10 km in 12 minute, and
another 40 km in 60 minute. What is his average velocity?
[Ans: 11.6 m/s)​

Answer 1

Answer:

Given already

Step-by-step explanation:

average velocity = change in velocity /change in time

But the question is wrong.

Correction of the question :-

A truck moving on East-West highway covers 10 km in 12 minute, and another 40 km in 60 minute.

What is the average speed?

Hence speed has to be found then only the answer is correct to the given answer.

• S = d/t
• we need average speed.so,
• s = total speed/total time
• s = 10+40/12+60
• s = 50/72

But the answer must be in m/s,So we need to multiply the Kms with 1000 and time with 60.

s = (50)1000/(72)60

s = 50000/4320

s = 11.6m/s

Hope it helps
