Step-by-step explanation:
the speed is 130 miles / hour.
that means the train travels 130 miles in 1 hour.
so, the question is, how far is it traveling. when it is going with that speed for 6 hours ?
well, 130 × 6 = 780 miles.
formally, speed is "distance / time".
multiplying this by some time, we have then an expression of "(distance / time) × time", which is then simply "distance".
Answer:
b
Step-by-step explanation:
it is the highest point but like its in the middle
Answer:
A) √((distance travelled due north)²+(distance travelled due east)²)
B) distance from starting point
C) Yes due west
Step-by-step explanation:
A) According to pythagoras theorem
resultant vector= √((distance travelled due north)²+(distance travelled due east)²)

B) The resultant vector tells the distance from the starting point
C) The same amount of distance travelled in opposite direction that is westwards will give same magnitude of resutlant vector.

Answer: 56 degrees
Step-by-step explanation:
We know that angle between b and c is 90 degrees. Because there is a line dividing angles a and b from 124 and c, we also know that each side is 180 degrees (a and b add to 180, and 124 and c add to 180).
124 and c are supplementary angles. We can represent this in an equation to solve for c:

Answer:
20g
since mass should be in kg or gram if small then g
