Speed is equal to 

• Distance/Time
• Time/Distance
• Time x Distance
• Acceleration

If a puppy runs across a park at a speed of 15 meters per second. The puppy has a time of 5 seconds. How far did the puppy run?

• 75 m

• 30 m

• 45 m

• 105 m

What is the equation to calculate time?

• time = speed/distance
• time = distance/speed 
• time = speed x distance 
• time = distance x speed
