Making Up Time: Solution

It is impossible to arrive on time. Doing the calculations will yield an answer of infinity. By driving at half the required speed the allotted time will be used up at the halfway point. For example, suppose that the time allowed for the journey is one hour then the distance would be 60 km and the half way point will be 30 km. Travelling at 30km/hr will take one hour to reach the half way point - therefore no time left.
