Question

a car travels 20 miles in 30 minutes, what is the cars average speed

Answer 1

Answer:

Speed is expressed as Distance over Time

Hence,

Average speed = total distance/total time

Average speed of car = 20 miles (distance) / 30 minutes (time)

Which can be rewritten by multiplying both distance and time by 2 as:

Average Speed = (20 x 2) miles / (30 x 2) minutes

Average Speed = 40 miles / 60 minutes

Average Speed = 40 miles / 1 hour (1 hour has 60 minutes)
