What is the formula to calculate speed?

• Speed = time/distance
• Speed = distance/time
• Speed = distance x time
• Speed = time x distance

When a car goes around a corner at 20 mph, why do we say it  accelerates?

• The car is accelerating because of the velocity is constant
• The car accelerates because it's going 20 mph
• Cars always accelerate when they are in motion
• The car is accelerating because it's changing direction
