Shivi drives her car on three different ways to reach the destination. Determine the average speed during this journey. Way Speed (Km/h) Distance (km) A 38 114 B 42 84 C 46 230

42.8 km/h 41.5 km/h 43.5 km/h 41.8 km/h

42.8 km/h

We know ,  Time = \(\frac{Distance }{Speed }\) Time 1 = \(\frac{114 }{38 }\) = 3 hours Time 2 = \(\frac{84 }{42 }\) = 2 hours Time 1 = \(\frac{230 }{46 }\) = 5 hours Average speed = \(\frac{114 + 84 + 230 }{3 + 2 + 5  }\) = \(\frac{428 }{10 }\) = 42.8 km/h
