t=3 hr
v=?
v=d/t

Answer 2

Heyya frnds.

__________

Lets see the answer there.

Speed = distance / time

So the distance of the rani s bicycle is 18 km in 3 hour

3 h = 18 km

Then in 1 hour = 18/3 = 6 km in one hour.

And if we want to speed in mtr / sec.

Then

1 hour = 60 min

Or

60 min = 3600 sec

We have 3 hour

Then 3 × 3600 = 10800 sec.

And the distance in km is 18.

1 km = 1000 mtr.

Then

18km = 18000mtr.

Distance = Mtr/ sec.

Then = 18000/10800

So the ans is

1.67 mtr in 1 sec.
