Algebra help please!

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

To solve this you would use the equation, d=r*t. So you would take 480=180*t. Or you could use t=480/180. The answer would come out to 2.66 hours, which means the answer would round up to 2.7 hours. The answer would be D.
