Ahigh-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

The number of hours it will take for the high-speed train to reach Grenoble is the ratio between the distance to the speed. For this item, the equation would be,
                                t = d / s
Substituting,
                                t = 480 km / 180 km/h = 2.7 h
Thus, it will take approximately 2.7 hours to reach Grenoble.
