Answer:

Yes, Chen earned a bonus for the journey.

Step-by-step explanation:

1 hour = 61 km

4.5 hrs = 61 * 4.5 = 274.5 km

Now,

96 litres = 274.5 km

1 litre = 274.5/96 km

1 litre = 2.859 = 2.9 km (approximately)

So, he drived more than 2.8 kilometers per litre of fuel.

Answer:

Yes

Step-by-step explanation:

Calculating distance travelled by Chen

  • Journey time x Average speed
  • 4.5 hours x 61 km/h
  • 274.5 km

Calculating distance covered per litre of fuel

  • Distance covered / Amount of fuel used
  • 274.5 / 96
  • 2.86 km/litre
  • The requirement was 2.8 km/litre
  • Therefore, Chen has earned a bonus for this journey
