Can someone help me with this question?
A car journey of 380 km lasts 4 hours. Part of this is on a motorway at an average speed of 110 kmh^-1, the rest on country roads at an average speed of 70 kmh^-1.
i) write this information as a pair of simultaneous equations
ii) solve your equations to find how many kilometres of the journey is spent on each type of road.
I can do the maths side of it, but am really struggling to pick out the key information and put it in the correct places to make a pair of equations
any help greatly appreciated
