Evaluate the speed (4)

I believe the answer is:

rate

I believe this is a double definition.

'evaluate' is the first definition.
(I know that rate is a more specific form of the action evaluate)

'the speed' is the second definition.
(both can mean pace)

(Other definitions for rate that I've seen before include "Fixed price or relative speed" , "Reckon; scold" , "Assess or grade" , "Charge per unit" , "Tariff" .)

I've seen this clue in the Evening Standard.
