Question 118446
It takes a local train 30 minutes longer than the express to travel 216km.The local averages 6km/h less than the express.What is a possible equation which could be used to determine the speed of each train?
I said 216/x-6 - 216/x = 30 but I was marked wrong :(
:
You have to convert 30 min to hrs
{{{216/((x-6))}}} + {{{216/x}}} = {{{1/2}}}
:
If you solve this you will get speeds of 48 and 54 km/hr
