Hello!
The answer is: 75 miles.
Why?
We can solver it solve it by using the following kinematic equation:
[tex]x=xi + v*t[/tex]
Assuming the starting point as 0 (it's our reference point), let's substitute the given information:
[tex]x=0+50*1.5=75 miles[/tex]
So, Bobs displacement is 75 miles.
Have a nice day!
