An object travels 20 m in 4 s and then another 20 min 10 s. What is the average speed of
the object?
Answers
Answer:
2.85 m/s.
Explanation:
Average speed= Total distance / Total time taken
Given - 20 m and 20 m = 20 + 20 = 40 m -------- TOTAL DISTANCE
4 s and 10 s = 4 + 10 = 14 s ---------- TOTAL TIME
Acc to the Formula -- Average speed = 40 / 14
= 2.85 m/s.
Answer:
2.89 m/s
Explanation:
first we will find the speed of both the objects, 20m/4sec= 5 m/sec 20m/10sec= 2m/sec average speed = total distance travelled divided by total time taken so 20+20=40 & 4+10=14 then we will divided them = 40 divided by 14= 2.89 m/sec
