Question

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

Answer 1

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.
