2000 km to 35780 km : M.E.O : : 180 km to 2000 km : ………

A car completed a journey of 5000 km. First 2000 km at 40 km/hr then next 1500 km at 60 km/hr and rest at 30 km/hr. Calculate the average speed of the journey?

Calculate the K.E, P.E, Total energy and Binding energy of an artificial satellite of mass 2000kg orbiting at a height of 3600 km above the surface of the earth Given: G = 6.67 xx 10^-11 Nm^2//kg R= 6400 km= 6.4 xx 10^6 m M= 6 xx 10^24 kg m = 2000 kg h = 3600 km = 3.6 xx 10^6 m

If a person covers 40 km at a speed of 10 km/h by a cycle, 25 km at 5 km/h on foot and another 100 km at 50 km/h by bus. Then, find his average speed for the whole journey?

An aerplane covers 2500 km,1200 km and 500 km at the rate of 500 km/hr ,400 km/hr and 250 km/hr respectively .Find its average speed for the whole journey.

A car covers 15 km, 20 km, 30 km and 12 km at speeds of 20 km/h, 30 km/h, 40 km/h and 30 km/h, respectively. The average speed of the car for the total journey is :

A man travels 600 km by train at 80 km/hr, 800 km by ship at 40 km/hr, 500 km by aeroplane at 400 km/hr and 100 km by car at 50 km/hr. What is the average speed for the entire distance? a. 60 k m//h r b. 62 k m//h r c. 60 5/(123) k m//h r d. 6 5/(123)k m//h r
