Neco 2022 Geography Question 14

Two possible routes connect point A to point D. **Route 1:** - Segment A‑B: 120 km. Speed limit 80 km h\(^{-1}\); however, for the first 30 km the speed is reduced by 20 % due to traffic. - Segment B‑C: 80 km on a secondary road with a nominal speed of 60 km h\(^{-1}\); road works reduce the speed by 15 % for the whole segment. - Segment C‑D: 50 km through a city where the average speed is 40 km h\(^{-1}\); a traffic signal adds a 5‑minute delay. **Route 2:** - Segment A‑E: 100 km on an expressway with speed 100 km h\(^{-1}\); a toll adds a 2‑minute delay. - Segment E‑F: 70 km on a rural road at 70 km h\(^{-1}\); a river crossing adds an 8‑minute delay. - Segment F‑D: 90 km on mixed roads with an average speed of 55 km h\(^{-1}\). Calculate the total travel time for each route (in minutes, rounded to the nearest minute), identify the faster route and state how many minutes earlier it arrives compared with the slower route.
