A50 മീ.

B75 മീ.

C65 മീ.

D25 മീ.

Answer:

D. 25 മീ.

Read Explanation:

Speed = distance / time

  • 1 മണിക്കൂറിൽ, 90km
  • 60 മിനിറ്റിൽ, 90km
  • 60 x 60 സെക്കന്റിൽ, 90km
  • 1 സെക്കന്റിൽ, എത്ര ദൂരം?

 

3600 sec = 90 km

1 sec = ?

? = (90 / 3600) km

? = (90 / 3600) x 1000

(km, m ലേക്ക് മാറ്റാൻ x 1000)  

= 90000/3600

= 25m
