Neco 2018 Civic Education Question 46
Practice objective / multiple choice question 46 from the 2018 Neco Civic Education examination.
A driver travels a straight road that passes through three consecutive zones. Zone A has a speed limit of 50 km/h and is 12 km long; Zone B has a speed limit of 80 km/h and is 20 km long; Zone C has a speed limit of 60 km/h and is 15 km long. The driver maintains a constant speed throughout the whole road. The traffic law imposes a fine in a zone equal to \( (v - \text{limit}) \times 100 \times \frac{\text{length}}{5} \) naira, where \(v\) is the driver's speed in km/h and the length is in kilometres. If the driver was fined a total of 12,000 naira and exceeded the speed limit in exactly two zones, determine his constant speed (in km/h).
