Question
Q:- A car travels with the following speeds with the following durations:
[1] with 6 meters/second for 6 seconds
[2] with 11 meters/second for 8 seconds
[3] with 19 meters/second for 8 seconds
[4] with 14 meters/second for 10 seconds
[5] with 12 meters/second for 7 seconds
[6] with 14 meters/second for 8 seconds
Find [1] total distance travelled , and [2] average speed
-
Step : 1
Distance travelled in each duration is as follows
[1] 6x6 = 36 meters
[2] 11x8 = 88 meters
[3] 19x8 = 152 meters
[4] 14x10 = 140 meters
[5] 12x7 = 84 meters
[6] 14x8 = 112 meters
Total distance travelled = 36 + 88 + 152 + 140 + 84 + 112 meters
= 612 meters
-
Step : 2
Total time travelled = 6 + 8 + 8 + 10 + 7 + 8 seconds
= 47 seconds
mean speed = total distance / total time
=> mean speed = 612 / 47 = 13.021276595745 meters/second
