1 Speedometer showS speed and odometer shows distance travelled, both velative to the surface on which the vehicle moves. Two conveyor-belts each of length L = 500 m are arranged along a line one after the other with a negligible gap. The belts are running in the same but unknown direction with constant speeds u1 = 20 km/h and u, = 30 km/h. A toy car installed with both the instruments runs on the belts one after the other spending t= 72 s on them. The speedometer shows constant readings or each of the belts and the odometer shows a total reading of s =L= 50 m. Find the speedometer readings on each of the belts,) 2CL-uで 20 Km! Belt 2; U, C Lu
