Question 990591
The original electric bullet train in Japan can travel 200 km/h.
 The newer trains can travel 270 km/h. 
 How much less time does it take the newer trains to travel 97 km from Tokyo to Mt. Fuji? 
:
Write a time equation, time = dist/speed
t = {{{97/200}}} - {{{97/270}}}
t = .485 - .359
t = .126 hrs which is .126(60) = 7.56 minutes less time
