The transformations that can occur to the graph of the function y = cos x that will exhibit changes would be changes to the angle, or changes to the coefficient. The transformations can be viewed as follows:
y = cos x transforms to y = cos (kx)
k > 1 ; a horizontal shrink occurs
0 < k < 1 ; a horizontal stretch occurs
y = cos x transforms to y = A cos x
|A| > 1 ; a vertical stretch occurs
|A| < 1 ; a vertical shrink occurs
1/6 = 0.1666, the last number repeating to infinity, or a repeating decimal.

Well, 217 miles ÷ 62 MPH is 3.5.
so it took the train 3.5 hours.
check it: 62 MPH x 3.5 hours, it went 217 miles
I hope this helps you
