Atrain leaves a station heading east at 50 mph from that same station a car drives north at a speed of 30mph after 3 hours how far apart are the two vehicles?

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

at the same time the distance moved by the car is given as

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

dopamine..
