Let speed of the 1st trip x miles / hr. and speed of the 2nd trip 3x / hr.

We know that

  • Speed = Distance/Time.
  • Or, Time = Distance/Speed.

So, times taken to covered a distance of 50 miles on his first trip = 50/x hr.

And times taken to covered a distance of 300 miles on his later trip = 300/3x hr.

= 100/x hr.

So we can clearly see that his new time compared with the old time was: Twice as much.

  • Hence, the option B is correct.
