Answer:
His new time compared to the old time was twice as much.
Step-by-step explanation:
Consider the provided information.
The distance covered in first trip is 50 miles.
The distance covered in later trip is 300 miles.
The relation between speed, time and distance is:[tex]Time=\frac{Distance}{Speed}[/tex]
Let speed of the first trip is x.
Thus, the speed of the later trip is 3x.
Now use the above formula by substituting distance 50 and speed as x.
[tex]T_1= \frac{50}{x}[/tex]
Similarly, time taken in second trip is:
[tex]T_2= \frac{300}{3x}[/tex]
Now, Compare new time with old.
[tex]\frac{50}{x}= \frac{300}{3x}[/tex]
[tex]\frac{50}{x}= \frac{100}{x}[/tex]
[tex]\frac{50}{x}= 2\times\frac{50}{x}[/tex]
Therefore, his new time compared to the old time was twice as much.
