Question

A train covers 240 meters in 8 seconds. find the speed of the train in km/hr​

Answer 1

Answer:

30km/hr

Step-by-step explanation:

Speed = distance/time

= 240/8

=30 speed

Answer 2

Given:-

• Distance = 240m
• Times = 8 seconds

To find:-

• Speed of the train in km/hr

Solution:-

We know,

$\sf{Speed = \dfrac{Distance}{time}}$

= $\sf{Speed = \dfrac{240}{8}}$

= $\sf{Speed = 30m/s}$

$\sf{To\: convert\: m/s\: into\: km/hr\: we\: need\: to\: multiply\: the\: unit\: with\: \dfrac{18}{5}}$

$\sf{Speed = 30 \times \dfrac{18}{5}}$

= $\sf{Speed = 108 km/hr}$

Extra Information:-

• $\sf{Distance = Speed \times Time}$

• $\sf{Speed = \dfrac{Distance}{time}}$

• $\sf{Time = \dfrac{Distance}{Speed}}$

• $\sf{To\:convert\:m/s\:into\:km/hr\:multiply\:the\:unit\:by\:\dfrac{18}{5}}$

• $\sf{To\:convert\:km/hr\:into\:m/s\:multiply\:the\:unit\:by\:\dfrac{5}{18}}$
