Question

pls solve these two problems with explanation​

Answer 1

Explanation:

18. velocity = distance/time

velocity of I = 10/20

velocity of II = 6/20

velocity of I/velocity of II = 10/6 = 5/3

option D is correct

19. distance = velocity * time

= 72*(5/18)*15

distance = 300 metre.

i think the options given in the problem 19 needs to be checked. since none of the options matches with the solution above.
