Best ResponseYou've already chosen the best response.0step 1. the radius of the orbit for satellite is the sum of the radius of the earth and distance above earth so orbit radius is: R = 1250 + 6400 = 7650 km Time taken for one revolution T = 110 mins = 110/60 = 11/6 hours (1 hr = 60 mins) step 2: total linear distance covered in one revolution of a radius R orbit is S = 2*pi*R (its perimeter of the the circular orbit pi = 22/7 approx) S = 2*(22/7)*7650 km step 3: linear speed = Linear distance / Total time taken = 2*(22/7)*7650 / (11/6) km/hr linear speed = 26228.57 km/hr
