Malcolm's maximum speed was 280 km/h and Ravi's maximum speed was 240 km/h.

Step-by-step explanation:

Step 1:

Assume Malcolm's maximum speed was x and Ravi's maximum speed was y.

The average of their maximum speeds was 260 km/h.

So

Take this as equation 1.

If their maximum speeds are doubled, Malcolm's maximum speed would be 80 km/h more than Ravi's.

So Take this as equation 2.

Step 2:

If we divide equation 2 by 2, we get

Take this as equation 3.

Substituting equation 3 in equation 1, we get

So Malcolm's maximum speed was 280 km/h and Ravi's maximum speed was 240 km/h.
