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. Find out his new time compared with the old time. Choose the correct choice from the following answers:
A) twice as much
B) three times 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.   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.   twice as muchnswer is twice as much.
