Question

certain distance is covered at certain speed S1 if
half of this distance is covered in double the time
S2 then find ratio of S1& S2 If S1 is 40km/hr
then find S2​

Answer 1

Answer:

Given:

Distance covered at speed S1 =40

let half of the distance is covered in double time be S2

To find :

ratio of S1 and S2

Solution:

S2=2(S1)

S2=2×40. (given)

S2=80

Now ,

S1\S2

= 40\80

=1\2

=1:2

ans therefore ratio of S1 and S2 is 1:2 .
