A train covers a distance of 9375 kms with uniform speed . The number of hours taken for the journey is \(\frac{3}{5}\) of the number of speed in km/h .  The time taken to cover the distance is ( in hours ) :

25 125 75 60

75

ratio of =    speed  :   time                     5     :     3 Distance  = Speed × Time 9375 = (5×) x (3x) x = 25 Time = 3x = 3 × 25 = 75 hours
