#141 Sam’s speed
Sam checked on his satnav and decided he could leave at 2pm for the 20-kilometre journey to the dentist. His appointment was at 2.30 (tooth hurty, boom-tish!). However, traffic that day was as sticky as the toffees his dentist had told him not to eat, and Sam spent the first 10 kilometres doing 30 kilometres per hour in a steady stream of traffic. Luckily, at the 10-kilometre mark, the road ahead miraculously cleared. What speed should Sam now maintain to arrive at his appointment on time?
