I am wary of answering questions like this directly because they look as if from a school pupil wanting us to do his or her homework.
Therefore I will tell you only how to answer it, which I think is the point.
Firstly, reject that data about direction. It misleads you into thinking, "Ah, co-ordinates" but since there is no further information in that regard we can treat the track's course as a red herring which we ignore.
The train is travelling for 1.5 hours at a steady 70km/hr.
Distance is the product of time and speed, and simple dimensional analysis shows that here, the answer will be xkm.

What is the velocitydistancespeed and displacement about this problem a car is moving to the north along to a straight highway and stops after 1 hour for refueling at a gasoline station 80 km?
Velocity: average of 80 km per hour due North, 0 when at station. Distance: 80 km. Speed : average of 80 km per hour, 0 when at station. Displacement: 80 km.
Give one type o f motion where distance and displacement are sane?
Linear motion -- motion and force occurring along a straight line. Otherwise, for example, when an object travels in a circular motion and returns to the starting point, the distance traveled = 2*pi*radius, but the displacement = 0. ==================================
What is the motion along a straight-line path?
I don't think there is a motion, but I think you are talking about vectors. In which case displacement is the measure of the change in position along a straight-line path.
What is the magnitude of the displacement of a car that travels half a lap along a circle that has a radius of 175 m?
Displacement is the straight line distance between two points. If the two points are a half a lap apart on a circular path then the straight line distance is the diameter of the circle; 350 m. What that means is that displacement describes only the relationship between end position and starting position, so the car stops at a point on the opposite side of the circle, 350m from the start. Displacement is not necessarily distance traveled. If the car had gone completely around the circle and stopped where it started, the displacement would be zero, even though it has traveled nearly 1100 m.
How light energy travels when it is released from an energy source?
Along straight lines, in all unblocked directions
Why does Rainbow appear round though light travels straight?
Light doesn't travel along the rainbow! It travels straight to your eye from every point of the rainbow. The points capable of producing a rainbow for a single individual observer happen to comprise a circular region in space.
According to Einstein's theory of relativity why does Mercury orbit the Sun?
Mercury travels along a straight path in the space warped by the mass of the sun.
Why does light travel in straight lines give with evidence?
Yes there is. Your shadow is the simplest evidence that light travels in straight line. A solar eclipse is also evidence that light travels in straight lines, as is the fact that you cannot see around corners unless you use a mirror.
What travels on the ecliptic?
the sun travels along the ecliptic
A body is moving along a circular path of radius 'R' What is the distance and displacement of the body?
The distance is how far the object travels in total, the displacement is how far the object is from its starting position as the crow flys. e.g. if you leave your house and walk 5 miles to the shop and then 5 miles back home again. your distance traveled will be 10 miles but your displacement will be 0.
What is the offset that occurs along a fault?
