Explanation

1. Let Ali's speed be x kmph. Then, the time taken by Ali to cover 30 km is 30/x hours.

2. Since Ali takes 2 hours more than Raza, the time taken by Raza to cover 30 km is (30/x) - 2 hours.

3. If Ali doubles his speed, his new speed is 2x kmph. The time taken by Ali to cover 30 km at this new speed is 30/(2x) hours.

4. According to the problem, if Ali doubles his speed, he would take 1 hour less than Raza. So, we can set up the equation:

(30/x) - 2 = (30/(2x)) - 1

Simplifying the equation, we get:

30/x - 2 = 15/x - 1

Multiplying both sides by x, we get:

30 - 2x = 15 - x

Simplifying further, we get:

x = 5

So, Ali's speed is 5 kmph.
