Answer:

By calculating the time taken to reach we get to know that the The time taken by the other person is less than yourself

Step-by-step explanation:

Given that the other person and yourself left at the same time and the speed of the other person is 60 miles per hour and the speed of yourself is 40 miles per hour.

We know that the $speed=\frac{distance}{time}$

Let the time taken to reach the destination at a distance of d by the other person is T1.

Then $60=\frac{d}{T1}$

$T1=\frac{d}{60}$

Let the time taken to reach the destination at a distance of d by the yourself is T2.

Then $40=\frac{d}{T2}$

$T2=\frac{d}{40}$

Now the time difference is = T2-T1 = $\frac{d}{60} -\frac{d}{40}$ = $-\frac{d}{120}$

Therefore T1 > T2 which means the time taken to reach the destination by yourself is greater than that of other person .
