A lorry is travelling at 13.5m/s along a stretch of road​

Mathematics

Answer:

Proved

Step-by-step explanation:

This question is incomplete. The complete details are:

v = 13.5m/s --- speed of the lorry

v_2 =50km/h --- 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:

v = 13.5m/s

1m = 0.001km

and

1s = \frac{1}{3600}h

So, the expression becomes:

v = \frac{13.5 * 0.001km}{1/3600h}

v = \frac{0.0135km}{1/3600h}

Rewrite as:

v = 0.0135km/h * 3600

v = 48.6km/h

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

<em>Hence, the lorry is within the speed limit.</em>
