A train travels 130 km in 2 hours. How much time it required to cover 520 km with the same speed?

Answer»

Time requires in travelling 130 km = 2 hours 

⇒ Time requires in travelling 1 km = (2/130) hours 

⇒ Time requires in travelling 520 km 

= (2 x 520/130) hours = 8 hours 

Thus, 8 hours required to cover 520 km with the same speed.
