Question

a boy travels with an average speed of 10 s-1 for 20 minutes. how much distance does he travel?​

Answer 1

Answer:

12 km

Step-by-step explanation:

Average speed of boy = 10 m/s

Average speed of boy = 10 m/sTime taken = 20 min = 20×60 =1200

Average speed of boy = 10 m/sTime taken = 20 min = 20×60 =1200 Using, Distance travelled = Speed × Time taken

Average speed of boy = 10 m/sTime taken = 20 min = 20×60 =1200 Using, Distance travelled = Speed × Time takenDistance travelled =10 m/s×1200 sec

Average speed of boy = 10 m/sTime taken = 20 min = 20×60 =1200 Using, Distance travelled = Speed × Time takenDistance travelled =10 m/s×1200 sec =12000 m

Average speed of boy = 10 m/sTime taken = 20 min = 20×60 =1200 Using, Distance travelled = Speed × Time takenDistance travelled =10 m/s×1200 sec =12000 m =12 km

Answer 2

Answer:

Average (v) = total distance traveled (s) / time taken (t)

v=s/t

according to the question,

average speed is given

and time is given

so the formula is > s= v×t

s = 10×20

s=30m

I think it is right

hopes it help you!!
