distance of 180 km in 4 hrs. Which car is moving faster?​

Answer 1

Answer:

car A is faster then the car b

Answer 2

Required Answer:

${\underline {\boxed {\huge {\rm{ Car \: A} }}}}$

Solution:-

→ In order to find which car is moving faster,we need to calculate their speed first.

For Car A :

As per the given question, we have:

• Distance covered (s) = 150km

• Time taken (t) = 3 hrs

Now, we know that,

• Speed = Distance/time or v = s/t

→ Speed of car A = 150/3

→ Speed of car A = 50 km/h

Therefore, speed of car A is 50 km/h.

For Car B :

As per the given question, we have:

• Distance covered (s) = 180 km

• Time taken (t) = 4hrs

Now, we know that,

• Speed = Distance/time or v = s/t

→ Speed of car B = 180/4

→ Speed of car B = 45 km/h

Therefore, speed of car B is 45 km/h.

Now, we can conclude that,

• Speed of car A is greater than car B.
• Speed of car A > Speed of car B

Therefore, Car A is moving faster.
