Speed of three train are in ratio 2 : 4 : 5 . Find the ratio of time taken by them . |
10 : 5 : 4 2 : 3 : 4 5 : 4 : 2 2 : 4 : 5 |
10 : 5 : 4 |
Speed = \(\frac{Distance}{Time }\) Ratio of speed and time is inverse to each other . given ratio T1 : T2 : T3 Speed 2 : 4 : 5 time \(\frac{1}{2 }\) : \(\frac{1}{4 }\) : \(\frac{1}{5 }\) 10 : 5 : 4 so ratio of time = 10 : 5 : 4 |
