Neco 2025 Geography Question 19

A city records an average of 200,000 vehicle trips per day. The current modal split is: cars 60%, motorcycles 15%, minibuses 10% and other modes 15%. A new Bus Rapid Transit (BRT) system is expected to attract 12% of car trips, 20% of motorcycle trips and 30% of minibus trips. Each attracted car trip reduces daily CO\(_2\) emissions by 0.25 kg, each attracted motorcycle trip by 0.15 kg and each attracted minibus trip by 0.20 kg. In addition, the remaining car trips (those not attracted to BRT) will experience a 10% reduction in per‑trip emissions because of smoother traffic flow; the original per‑car‑trip emission is 0.30 kg. Calculate the total reduction in daily CO\(_2\) emissions (in kilograms) after the BRT system becomes operational.
