Answer:
To calculate the estimated arrival time in Newcastle, we need to divide the distance by the average speed of the car.
Given that the distance from Leeds to Newcastle is 160 kilometers and the car averages 50 km/h, we can use the formula:
Time = Distance / Speed
Time = 160 km / 50 km/h
Time = 3.2 hours
Now, we need to add this time to the departure time of 1:00 PM:
1:00 PM + 3.2 hours = 4:12 PM
Therefore, the car will arrive in Newcastle at approximately 4:12 PM.
