Answer:
The answer is 30m per second
Explanation:
The sum of distances = 20 +160 = 180m
The sum of time = 2s + 4s = 6s
The speed = 180m/6s
=30m/s

ɢɪᴠᴇɴ :-
An object covers a distance of 20m in first 2 seconds and then 160m in the next 4s.
ᴛᴏ ғɪɴᴅ :-
- Average Speed
sᴏʟᴜᴛɪᴏɴ :-
Now,
Condition-1
- Distance(d1) = 20m
- Time taken(t2) = 2 seconds
Condition-2
- Distance(d2) = 160m
- Time taken(t2) = 4s
We know that,
Average speed = Total distance travelled / Total Time taken
➮ Average speed = (d1 + d2 ) /( t1 + t2)
➮ Average speed = (20 + 160) / (2 + 4)
➮ A. S. = 180/6
➮ Average speed = 30 m/s
Hence,
- Average speed is 30 m/s
