Question

35) If the ratio of the speeds of A and
B is a:b, then the ratio of the times
taken by them to cover the same
distance is
O (a) b: a
O (b) (b+1) : (a+1)
O (c) (a+1) : (b+1)
O (d) 2a : 3b
​

Answer 1

Answer:

(a) b: a

Step-by-step explanation:

let  speed be ax and bx respectively of A and B

and distance =d

time taken by A = d/ax

Time taken by B =d/bx

and their ratio is d/ax : d/bx

=b:a
