Answer:

Explanation:

The distance traveled by the car at an average speed of 160 km/h for 2 hours and 45 minutes can be calculated as follows:

Distance = Speed × Time

Distance = 160 km/h × (2.75 hours)

Distance = 440 km

Now, we need to find the speed at which the car must drive to travel the same distance in 2 hours and 35 minutes (i.e., 2.5833 hours).

Distance = Speed × Time

440 km = Speed × (2.5833 hours)

Solving for speed, we get:

Speed = Distance / Time

Speed = 440 km / 2.5833 hours

Speed ≈ 170.1 km/h

Therefore, the car must drive at a constant speed of approximately 170.1 km/h to travel the same distance in 2 hours and 35 minutes.
