Ramesh covers a distance in certain time 't'. If 2/3 of the distance is covered in 1/3rd of the time (with speed s1) and rest of the 1/3 distance is covered in 2/3rd of the time (with speed S2), what will be the ratio of the two speeds (S1, : S2,)?

Answer:
let distance covered be x
tme taken is t
In first case
distance =2/3x
time =1/3t
speed=distance/time
S1=(2/3x)/1/3t
S1=2xt
In second case
distance=1/3x
time=2/3t
speed=(1/3x)/2/3t
S2=xt/2
ratio of S1 and S2=2xt÷xt/2
=4:1
