Alorry is travelling a 13.5m/s along a stretch of road where the speed limit is 50km/h. show that the lorry is traveling below the speed limit.

Step-by-step explanation:

We have been given that a lorry is travelling a 13.5 m/s along a stretch of road where the speed limit is 50 km/h.

Let us convert speed of lorry into km/h. Since 1 hour equals 3600 seconds, so we will multiply 13.5 by 3600 to find the distance traveled by lorry in 1 hour

1 km = 1000 meters

So to convert speed of lorry into km/h we will divide distance covered by lorry in 1 hour by 1000.

Since lorry's speed is 48.6 km/h which is less than speed limit of 50 km/h, therefore, we can say that the lorry is traveling below the speed limit.
