Hello,

SPEED = DISTANCE / TIME

Speed = ?

Radius = 14cm

Circumference or distance = 2 pi r

= 2 × 22/7 × 14

= 2 × 22 × 2

= 88 cm

= 0.88m

Time = 1 hour = 3600 seconds

SPEED IN THIS CASE = 0.88/ 3600

SPEED = 0.00024444...m/s or 0.02444444..... cm/s

muskaeyy: plzz can you give me one more solu of one more plzzz can you and thanku for giving me ans of this question

muskaeyy: i am sending question

muskaeyy: a car travels a distance of 60 km in 5 hours what is his speed in metre per second

gghg1811p2jn4e: distance = 60 km = 60000m

gghg1811p2jn4e: Time = 5 hours = 18000 seconds

gghg1811p2jn4e: Speed = distance / time

gghg1811p2jn4e: Speed = 60000/ 18000 = 10/3 m per s

gghg1811p2jn4e: or

gghg1811p2jn4e: 3.3333..... m/ s
