Answer:
Proved
Step-by-step explanation:
This question is incomplete. The complete details are:
--- speed of the lorry
--- speed limit on the road
Required
Prove that the lorry is within the speed limit
To do this, we simply convert the speed of the lorry to km/h.
So, we have:


and

So, the expression becomes:


Rewrite as:


<em>48.6km/h is less than 50km/h (the speed limit).</em>
<em>Hence, the lorry is within the speed limit.</em>
