1 answer:
<u>Answer:</u>
<em>The truck is going 40 km/h faster than the speed limit. </em>
<u>Explanation:</u>
The fixed speed limit = <em>60km/h</em>
distance travelled by the truck = <em>10 km</em>
time taken <em>t=6 minutes</em>
we have convert 6 minutes into hour
<em>1 hour=60 minutes </em>
<em>1 minute=1/60 hour </em>
<em>6 minute=6/60 hour=1/10 h </em>
Speed is obtained by dividing distance covered by time.
<em> speed = distance/time = =100 km/h
</em>
<em>difference between the speed of the car and the speed limit</em>
<em>=100-60 = 40km/h </em>
