A. 50 minutes

Answer :

Final answer:

The distance of the journey is 66.67 km. Traveling at 80 km/h, it will take 50 minutes to cover that distance, making option (A) the correct answer.

Explanation:

The journey takes 40 minutes at 100 km/h, we can calculate the distance:

Distance = Speed × Time = 100 km/h × (40/60) h = 66.67 km

Now let's calculate the time it would take to travel the same distance at 80 km/h:

Time = Distance / Speed = 66.67 km / 80 km/h = 0.8333 hours

To convert hours into minutes, we multiply by 60:

Time in minutes = 0.8333 h × 60 min/h = 50 minutes

Therefore, the travel time when going at 80 km/hr would be 50 minutes, corresponding to option (A).
