Neco Model Questions Vol1 2023 Civic Education Question 43

Traffic Regulations (Hard): A driver can travel from point X to point Y via two possible routes. *Direct route*: passes through three speed‑limit zones - Zone A (limit 50 km h(^{-1}\), distance 12 km), Zone B (limit 80 km h(^{-1}\), distance 20 km), and Zone C (limit 60 km h(^{-1}\), distance 8 km). The driver travels at the posted limit in each zone. *Detour*: avoids Zone B and adds an extra 5 km stretch travelled at 60 km h(^{-1}\). The driver still travels at the posted limits in Zones A and C. Police enforce a penalty when the driver's average speed for the whole trip exceeds 60 km h(^{-1}\). Compute the average speed for each route (to one decimal place) and state for each route whether the driver would be penalised.
