Question

a velocity of 20km/h is represented by an arrow of length 5 cm. what velocity is represented by an arrow of length 7.5 cm?

Answer 1

Answer:

The answer is 30 km/hr.

Explanation:

Velocity is defined as the distance covered in unit time. Its S.I unit is ms-1.

Given data:

For 5 cm = 20 km/hr

Let suppose for 7.5 cm the distance covered is x

Therefore, x = (7.5×20)÷5  

                   = 150 / 5  

                  = 30 km/hr

Thus for 7.5 cm the velocity will be 30 km/hr.
