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
