Given, x takes 3 hours more than y to cover 30km.
According to question, x + 3 = y OR x = y - 3
If x doubles his pace, he is ahead of y by 1.5 hours.
So, the equation formed is
2x = y + 1.5
2(y-3) = y + 1.5
2y - 6 = y + 1.5
2y - y = 1.5 + 6
y = 7.5
Hence, speed of y was 7.5km/h and speed of x was 10.5km/h.
Hope it helps.
