Question

Which of the two is moving faster -(a) A car going over a distance of 400km in 5hours, or (b) A train covering a distance of 500km in 6hours?

Answer 1

Answer:

Train

Explanation:

In order to find out which vehicle is moving faster, we'll have to calculate their speeds and then we'll compare their speeds to find out the answer,

(a) A car going over a distance of 400km in 5hours.

• Distance, s = 400 km
• Time, t = 5 hours

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

$\longrightarrow\sf{v_1=\cancel{ \dfrac{400 \; km}{5 \; h}}}$

$\longrightarrow \underline{\boxed{\sf{\blue{v_1= 80 \; kmh^{-1}}} }}$

Therefore, speed of the car is 80 km/h.

(b) A train covering a distance of 500km in 6hours.

• Distance, s = 500 km
• Time, t = 6 hours

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

$\longrightarrow\sf{v_2=\cancel{ \dfrac{500 \; km}{6 \; h}}}$

$\longrightarrow \underline{\boxed{\sf{\blue{v_2= 83.3 \; kmh^{-1}}} }}$

Therefore, speed of the train is 83.3 km/h.

Now, we found that :

• Speed of train [83.3 km/h] > Speed of car [80 km/h]

Therefore, train is moving faster.

Answer 2

QUESTION :-

• Which of the two is moving faster -(a) A car going over a distance of 400km in 5hours, or (b) A train covering a distance of 500km in 6hours?

GIVEN :-

• A car going over a distance of 400km in 5hours
• A train covering a distance of 500km in 6hours?

TO FIND :-

• Which of the two is moving faster = ?

SOLUTION :-

A car going over a distance of 400km in 5hours

so, Let us do this question :-

vehicles covered the distance = 400 km

taken time = 5 hours

then, we have to divide 400 km with

5 we get :-

400km/ 5hour

= 80km/hr

A train covering a distance of 500km in 6hours

so, Let us do this question :-

train covering a distance = 500 km

taken time = 6 hours

then, we have to divide 500

with 6 we get :-

= 500km/6hours

= 83.3 km/h

so, moving faster is train
