| Option | 15 km | incorrect |
| Option | 19 km | correct |
| Option | 23 km | incorrect |
| Option | 25 km | incorrect |
Total distance travelled = Average speed * Total time taken to complete the journey
Average speed =
Total time taken = 4 hour 45 minutes =285⁄60 =19⁄4hour
So, Total distance travelled = 8 *19⁄4= 38 km
Distance between village and city will be half of the total distance travelled: So, distance between village and city =38⁄2 = 19 km (Option B)
