Answer:
Malcolm’s maximum speed is 200 km/h and and Ravi’s maximum speeds is 320 km/h.
Step-by-step explanation:
Let x and y are the maximum speeds ( in km / h ) of Malcolm and Ravi respectively,
Then according to the question,
Again according to the question,
Equation (1) + equation (2),
3x = 600
⇒ x = 
= 200,
From equation (1),
200 + y = 520
⇒ y = 520 - 200 = 320
Hence, Malcolm’s and Ravi’s maximum speeds are 200 km/h and 320 km/h respectively.

Equivalent expressions are expressions with equal values
The equivalent expression is 16.5d+9
<h3>How to determine the equivalent expression</h3>
The expression is given as:
14.5d+8.5-1/2d+1/2+2.5d
Express the fractions as decimals
14.5d+8.5-0.5d+0.5+2.5d
Collect like terms
14.5d-0.5d+2.5d+8.5+0.5
Evaluate the like terms
16.5d+9
Hence, the equivalent expression is 16.5d+9
