What were Malcolm's and Ravi's maximum speeds?

Malcom's maximum speed = 200 km/h

Ravi's maximum speed = 320 km/h

Step-by-step explanation:

Let m = Malcom's maximum speed

Let r = Ravi's maximum speed

Average of their maximum speed would be represented as

.

Make m the subject of the formula by subtracting r from both sides:

. Let this be equation 1.

Given that Malcom's speed (m), when doubled is 80 km/h more than that of Ravi (r). This can be expressed as: . This is equation 2.

Plug in (520 - r) into equation 2 to replace m:

Solve for r. Subtract 1040 from both sides:

Subtract r from both sides

Divide both sides by -3

To find m, plug in the value of r into equation 1.

. =>Equation 1

.

Malcom's maximum speed = m = 200 km/h

Ravi's maximum speed = r = 320 km/h
