Answer:
d = 175 miles
Explanation:
Train is moving towards East with constant speed of 50 mph
While car is moving at speed of 30 mph
so after t = 3 hours
the distance moved by the train is given as
![d_1 = vt](https://tex.z-dn.net/?f=d_1%20%3D%20vt)
![d_1 = (50)(3) = 150 miles](https://tex.z-dn.net/?f=d_1%20%3D%20%2850%29%283%29%20%3D%20150%20miles)
at the same time the distance moved by the car is given as
![d_2 = 30(3) = 90 miles](https://tex.z-dn.net/?f=d_2%20%3D%2030%283%29%20%3D%2090%20miles)
now we know that both car and train is moving perpendicular to each other
So the distance between them after t = 3 hours is given as
![d= \sqrt{d_1^2 + d_2^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7Bd_1%5E2%20%2B%20d_2%5E2%7D)
![d = \sqrt{150^2 + 90^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B150%5E2%20%2B%2090%5E2%7D)
![d = 175 miles](https://tex.z-dn.net/?f=d%20%3D%20175%20miles)
