You can put this solution on YOUR website! What is the average speed of a plane that takes 1hr & 40min to travel 800km?
what working out did you use?
Sol'n:
Average speed (s) = total distance/total time
first, convert 40 min, to in terms of hour so, it is equal to 2/3 hr.
then:
s = 800 km/ 1 & 2/3 hr.
s = 480-km/hr ----answer
or
s = 133.33 m/sec----answer
