Question

An object travels 10 m in 5 sec and another 10 m in 8 sec. What is the

average speed of the object?​

Answer 1

Answer:

1.53 m/s

Explanation:

As per the provided information in the given question, it has been given to us that,

• An object travels 10 m in 5 sec and another 10 m in 8 sec.

We are asked to calculate the average speed of the object.

Average speed of the object is nothing the total distance travelled divided by total time taken.

Here,

➝ Total distance travelled = 10 m + 10 m

➝ Total distance travelled = 20 m

And,

➝ Total time taken = 5s + 8s

➝ Total time taken = 13 s

Now, we have to apply the formula of average speed to calculate the average speed of the object.

★ Average Speed = Total distance ÷ Total time

→ Average Speed = 20 m ÷ 13s

→ Average Speed = 1.53 m/s

More Information :

• Speed is defined as distance travelled in per unit time.
• It is a scalar quantity.
• Its SI unit is m/s.
• It is denoted by v.
• Average speed refers to the total distance travelled divided by total time taken.
