Mohan travels three equal distances at speeds of 12 km/h, 18 km/h and 24 km/h. If he takes a total of 13 hours, then what is the total distance covered? |
212 km 216 km 214 km 218 km |
216 km |
Let equal distance = x ATQ , Time = \(\frac{Distance }{Speed}\) \(\frac{x }{12}\) + \(\frac{x }{18}\) + \(\frac{x }{24}\) = 13 \(\frac{6x + 4x + 3x }{72}\)= 13 13x = 936 x = \(\frac{936 }{13}\) = 72 km Total distance = 3x = 3 × 72 = 216 km |
