A high-speed train travels 480 km from Paris to Grenoble, France, at an average speed of 180 km/h. How long will it take to reach Grenoble?

A. 0.66 h
B. 3.8 h
C. 0.38 h
D. 2.7 h

Respuesta :

The time (t) it will take for the train to reach to Grenoble is the quotient when the distance (d) is divided by the speed (s). That is,
                                       t = d / s
Substituting the known values,
                                       t = 480 km / 180 km/h
                                      t = 2.667 h
Thus, it will take approximately 2.7 h to reach Grenoble. The answer is letter D.
