Answer:
See explanation
Explanation:
distance = 3 kilometres
time = 30 minutes or 0.5 hours
speed = distance/time = 3/0.5 = 6 Kmhr-1
Average speed is given by total distance covered divided by the total time taken while the instantaneous speed is the speed of an object at a particular instant or moment in time. Average speed refers to the whole journey while instantaneous speed refers to a particular point or instant in the journey.
distance= x
time = 3 hours
speed = 50 miles per hour
speed = distance/time
distance = speed * time
distance = 3 * 50
distance = 150 miles
