Question

What is the displacement of a car in 30 s if it is travelling with
velocity of 15 m/s?
​

Answer 1

average velocity = displacement ÷ time

15 = x ÷ 30

x = 15 × 30

x = 450

so displacement is 450 m

hope it is helpful

Answer 2

$\bigstar$ Given

Velocity = 15 m/s

Time = 30 s

$\bigstar$ To Find

Displacement

$\bigstar$ Solution

We know that

$\red{\sf \longrightarrow d=v \times t}$

Here

• d = displacement
• v = velocity
• t = time

Units

• d = metre (m)
• v = metres per second (m/s)
• t = seconds (s)

According to the question

We are asked to find displacement

Therefore

We must find "d"

Given that

Velocity = 15 m/s

Time = 30 s

Hence

• v = 15 m/s
• t = 30 s

Substituting the values

We get

$\orange{\sf \longrightarrow d=15 \times 30 \ m}$

Therefore

$\pink{\sf \longrightarrow d=450 \ m}$

Hence

$\checkmark$ Displacement = 450 m
