Answer: 55.6m per hour
Step-by-step explanation:
The equation for finding the distance is distance = speed x time
since speed is given in km convert in into meters by multiplying 100 by 1000 since 1km= 1000m
then speed will be 100 000m per hour
next convert the time which is in seconds to hours by dividing 2 by 3600 so then the time in hours will be 0.000555556 hours
so now all you have to do is follow the distance equation I mentioned before
Distance= 100 000 x 0.000555556
= 55.5556
next you have to leave the answer in the 3sf (this is a rule u have to follow when dealing with REALLY long decimal so dw but remember)
so the final answer will be: 55.6m per hour
