Answer 2

$\checkmark$ Given:

A body travels 30 metre in 2 second and then travels 40 metre in 5

seconds

$\checkmark$ To Find:

The average speed

$\checkmark$ Solution:

We know that,

$\red{\bigstar \ \boxed{\rm s=\dfrac{d}{t}}}$

Here,

• s = speed
• d = distance
• t = time

According to the question,

We are asked to find the average speed

So, we must find "s"

Given that,

A body travels 30 metre in 2 second and then travels 40 metre in 5

seconds

Hence,

• d = 30 + 40 = 70 m
• t = 2 + 5 = 7 s

Substituting the values,

We get,

$\blue{\rm \implies s=\dfrac{70}{7} \ m/s}$

$\pink{\rm \implies s=10 \ m/s}$

Therefore,

The average speed = 10 m/s
