Hello!
Kinematics by definition is the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
If you travel at a constant speed, you follow this equation:
![d = st](https://tex.z-dn.net/?f=%20d%20%3D%20st%20)
where d is the distance, s is the speed and t is the time.
In this example, you first travel 60 miles per hour for 45 minutes. Since 45 minutes are 3/4 of a hour, you will cover a distance of
![d_1 = 60\cdot\dfrac{3}{4} = 45](https://tex.z-dn.net/?f=%20d_1%20%3D%2060%5Ccdot%5Cdfrac%7B3%7D%7B4%7D%20%3D%2045%20)
In the second part, since 30 minutes is half a hour, you will cover a distance of
![d_2 = 50\cdot\dfrac{1}{2}=25](https://tex.z-dn.net/?f=%20d_2%20%3D%2050%5Ccdot%5Cdfrac%7B1%7D%7B2%7D%3D25%20)
So, in total, you travel
miles
