Model answer
What a good answer should say
- The estimated average speed is 75 km/h, which is realistic for highway driving.
Explanation
Why this works
This question tests the ability to estimate average speed using the formula speed = distance/time. The substitution of 150 km for distance and 2 hours for time leads to a calculated average speed of 75 km/h, which aligns with typical highway speeds.
