Nothing. Makes the engine rev higher.
By changing direction. Acceleration is a change in velocity. Since velocity takes direction into account, while speed does not, an object can having a changing velocity even while its speed remains the same. And while that object is changing its velocity by changing its direction, it is accelerating, regardless of its speed remaining constant. For example, if a car is driving north at constant speed of 20mph, its speed is 20mph, while its velocity is 20mph towards the north. At this point, the car is not accelerating. Now if the car turns a corner to head east while maintaining its speed of 20mph, its velocity is changing from 20mph northward to 20mph north-eastward and finally to 20mph eastward. As it is turning, it is accelerating. However, as soon as it stops turning, the car is no longer accelerating.
well you will get 20 miles in an hour, so it is 1/20 of an hour to go 1. This is 3 minutes
The time it takes to drive 511 miles depends on the speed at which you are traveling. If you are driving at a constant speed of 60 miles per hour, it would take approximately 8.5 hours to cover 511 miles. However, if you are traveling at a speed of 70 miles per hour, it would take around 7.3 hours to complete the same distance. Keep in mind that these calculations assume no stops or delays during the journey.
20mph
depends, if that was the constant speed at all times uphill and downhill, and the times are both the same. then the average speed would be 15mph
20mph
