Question

A Japanese bullet train recently maintained an average speed of 317.5 km/h for a trip lasted 3h 15 min. Calculate the distance covered by the train on that trip.

Answer 1

Hi there Jo!

     So for your question recall the distance formula. Distance = Rate * Time

To make things easier convert the time given to hours alone so that the units (hours) will cancel out leaving just km. To do this take the minutes and divide it by 60 to get the decimal value of 15mins/60mins. 15/60 simplifies to 1/4 or .25

 

D = R * T

D = (317.5 km/h) * (3.25 hrs) = 1,031.875 km

 

 Hope this helps and I am available for further online tutoring help!

 

Best of luck,
