Radius =r =42250km
Time =24hr
Distance covered around the earth for one revolution = circumference of the earth =d = 2*pi* r
Speed = d/t
= (2*pi*r)/t
=(2*22/7*42250)/24
=(2*22*42250)/(7*24)
=1580.78 km/hr
Time =24hr

Hey there!
Given,
Radius (r) = 42250 km
Time (t) = 24 hours
Distance will equal to perimeter of the orbit
= 2πr
= 2π * 42250
Speed of artificial satelite
= 2π * 42250/24
= 11059 km/h
Hope It Helps You!
