Question 1: What is the velocity of a car that traveled a total of 75 kilometers north in 5 hours? Solution: Velocity = distance / time = 75 km / 5 hr = 15 km/hr north Question 2: What is the velocity of a plane that traveled 3,000 miles from New York to California in 5.0 hours? Solution: Velocity = distance / time = 3000 miles / 5 hr = 600 miles/hr west Question 3: John took 45 minutes to bicycle to his grandmother's house, a total of four kilometers. What was his velocity in km/hr? Solution: Convert 45 minutes to hours: 45 minutes / 60 minutes/hour = 0.75 hours Velocity = distance / time = 4 km / 0.75 hr = 5.3 km/hr Question 4: How many miles lie between the two cities? Solution: Distance = velocity * time = 120 miles/hr * 3.5 hr = 420 miles Question 5: How long would it take for a car to travel a distance of 200 kilometers if it is traveling at a velocity of 55 km/hr? Solution: Time = distance / velocity = 200 km / 55 km/hr = 3.63 hours Question 6: A car is traveling at 100 km/hr. How many hours will it take to cover a distance of 750 km? Solution: Time = distance / velocity = 750 km / 100 km/hr = 7.5 hours Question 7: A plane traveled for about 2.5 hours at a velocity of 1200 km/hr. What distance did it travel? Solution: Distance = velocity * time = 1200 km/hr * 2.5 hr = 3000 km Question 8: A girl is pedaling her bicycle at a velocity of 0.10 km/min. How far will she travel in two hours? Solution: Convert 2 hours to minutes: 2 hours * 60 minutes/hour = 120 minutes Distance = velocity * time = 0.10 km/min * 120 minutes = 12 km Question 9: An ant carries food at a speed of 1 cm/s. How long will it take the ant to carry a cookie crumb from the kitchen table to the ant hill, a distance of 50 m? Express your answer in seconds, minutes, and hours. Solution: Convert 50 meters to centimeters: 50 m * 100 cm/m = 5000 cm Time = distance / speed = 5000 cm / 1 cm/s = 5000 seconds Convert seconds to minutes: 5000 seconds / 60 seconds/minute = 83.33 minutes Convert minutes to hours: 83.33 minutes / 60 minutes/hour = 1.39 hours Question 10: The water in the Buffalo River flows at an average speed of 5 km/hr. If you and your friend decide to canoe down the river a distance of 16 kilometers, how many hours and minutes will it take? Solution: Time = distance / velocity = 16 km / 5 km/hr = 3.2 hours Convert hours to minutes: 0.2 hours * 60 minutes/hour = 19.2 minutes Therefore, it will take 3 hours and 19 minutes.
