The fuel consumed by a motorcycle during a journey while traveling at various speeds is indicated in the graph below. The distances covered during four laps of the journey are listed in the table below From the given data, we can conclude that the fuel consumed per kilometre was least during the lap
Lap Distance (kilometers) Average speed (kilometers per hour) P 15 15 Q 75 45 R 40 75 S 10 10
To determine the lap during which the fuel consumed per kilometer is the least, we need to understand the relationship between speed and fuel consumption as indicated by the graph and the data in the table.
The graph shows fuel consumption (in kilometers per litre) versus speed (in kilometers per hour). The key point is to identify which speed results in the highest fuel efficiency, i.e., the maximum kilometers per litre, which corresponds to the least fuel consumed per kilometer.
From the graph:
- At 15 km/h, the fuel consumption is approximately 45 km/l.
- At 45 km/h, the fuel consumption is approximately 90 km/l.
- At 75 km/h, the fuel consumption decreases again, indicating lower km/l.
From this observation:
- The highest fuel efficiency (90 km/l) occurs at 45 km/h.
Now, compare this with the table:
| Lap | Distance (kilometers) | Average speed (kilometers per hour) |
| P | 15 | 15 |
| Q | 75 | 45 |
| R | 40 | 75 |
| S | 10 | 10 |
The average speed during lap Q is 45 km/h, which corresponds to the highest fuel efficiency observed from the graph (90 km/l). Therefore, the fuel consumed per kilometer is the least in lap Q.
Thus, the correct answer is Q.
