A bus moves away from a bus stop in a straight line. it moves 10 meters by the end of the 1st second, 20 meters by the end of the 2nd second, and 30 meters by the end of the 3rd second. how many meters away is the bus from the bus stop after 10 seconds?

the bus moves 10 m per second, so the number of meters moved is 10x, x being the number of seconds.

10x = 10*30    (because it's 30 seconds)
10*30 = 300
300 meters
