Jones covered a distance of 50 miles on his first trip. On a later trip he traveled 300 miles while going three times as fast. His new time compared with the old time was: Choose the correct choice from the following choices: A) three times as much B) twice as much C) the same D) half as much E) A third as much
Let speed of the 1st trip x miles / hr. and speed of the 2nd trip 3x / hr.   Speed = Distance/Time.   I.E Time = Distance/Speed.   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.CORRECT ANSWER : twice as much
