Answer:
7.33 m/s
Explanation:
Given :
- The body travels a distance of 20 metres in 5 seconds
- The body travels a distance of 25 metres in 7 seconds
- The body travels a distance of 65 metres in the last 3 seconds
To find :
- Average speed of the body
Average speed = total distance / total time
Total distance = 20+25+65
Total distance = 45+65
Total distance = 110 metres
Total time = 5+7+3
Total time = 5+10
Total time = 15 seconds
Average speed = 110/15
Average speed = 7.33 m/s
The average speed of the body is equal to 7.33 m/s
