Question

If a body travels at a constant velocity of 60 km/h in the 30 seconds.find the distance travelled by the body in metres?.

Answer 1

Given :

• Velocity = 60 km/h
• Time = 30s

To Find :

• Distance travelled by body.

Solution :

$\longrightarrow \sf{Speed \: = \: 60 \: kmh^{-1}}$

ㅤㅤㅤㅤㅤㅤㅤ

$\longrightarrow \sf{Speed \: = \: 60 \: \times \: \dfrac{5}{18} \: ms^{-1}}$

ㅤㅤㅤㅤㅤㅤㅤ

$\longrightarrow \sf{Speed \: = \: 16.67 \: ms^{-1}}$

______________________

$\longrightarrow \boxed{\boxed{\sf{Speed \: = \: \dfrac{Distance}{Time}}}}$

ㅤㅤㅤㅤㅤㅤㅤ

$\longrightarrow \sf{Distance \: = \: Speed \: \times \: Time}$

ㅤㅤㅤㅤㅤㅤㅤ

$\longrightarrow \sf{Distance \: = \: 16.67 \: \times \: 30}$

ㅤㅤㅤㅤㅤㅤㅤ

$\longrightarrow \sf{Distance \: = \: 500}$

ㅤㅤㅤㅤㅤㅤㅤ

$\underline{\underline{\sf{\therefore \: Distance\ travelled\ is\ 500\ m}}}$

Answer 2

Answer:

Let me help you for this question....

Given :

Speed = 60 km/hr = 60 × 5/18  m/s

Time = 30 secs

=> Distance travelled = Speed × Time

=> Distance travelled = 300 × 30 / 18 = 9000/18 m

Therefore the distance travelled is 500m
