Question

the above attachment contains my question, please answer properly​

Answer 1

Answer:

3000/900= 10/3= 3.33 m/s

Explanation:

total distance between Golu and bholu house is =9km

distance covered by bholu in 40 minutes= 6 km

therefore the remaining distance is 3 kilometre or 3000 metre.

since Golu talks to Chintu for 5 minutes the total time taken to cover 6 kilometre is 45 minutes therefore remaining time is 15 minutes or 900 seconds.

we know that speed=distance/time

therefore V=3000/900 =3.3 m/s

bolu c covered his second part of journey with 3.3 metre per second.

average speed is the total distance covered in total time so,

total distance=9000 metre

total time = 60×60=3600 sec

avg speed = total distance/total time

Vavg=9000/3600= 2.5 m/s

if you understood the answer then mark it

as brainliest

thank you!
