Question

Calculate the velocity of a car when it covers 3km in 5 minutes​

Answer 1

Explanation:

$\huge\underline\green{Answer}$

Speed = distance/time. = 300000 cm/ 300 sec. = 1000 cm/s.

3 km = 3000m and 5 min = 300 sec. speed = 3000/300 = 10 m/s.

3 km = 3 km and 5 min = 1/12 h.

hence proved

Answer 2

Explanation:

Velocity = Displacement/Time

Here, Displacement = 3km and Time = 5min.

So, Velocity = 3km/5min

Now, firstly we have to convert the unites either 3 km into metre and 5 minutes into seconds or 5 minutes into hour.

1) When we convert km into m and min into sec.

Velocity = 3 x 1000/ 5 x 60

Velocity = 10 m/sec.

2) When we convert minute into hour.

Velocity = 3 x 60/5

Velocity = 36 km/h

Hope it helps..!! ☺
