A runner completes a 400-meter lap around a track in 50 seconds. What is the runner's speed in meters per second?
Speed = Distance * Time
400 meters * 50 seconds = 2000 m/s.
Speed = Distance / Time
400 meters / 50 seconds = 7 m/s.
Speed = Distance / Time
400 meters / 50 seconds = 8 m/s.
Speed = Distance * Time
400 meters * 50 seconds = 20,000 m/s.
A cyclist travels a distance of 20 kilometers in 1 hour and 15 minutes. What is the cyclist's average speed in kilometers per hour? HINT: convert second into hrs
First, convert 1 hour and 15 minutes to hours: 1 hour + (15 minutes / 60) = 1.25 hours. Speed = Distance / Time = 20 km / 1.25 hours = 16 km/h
First, convert 1 hour and 15 minutes to hours: 1 hour + (15 minutes / 60) = 1.15 hours. Speed = Distance / Time = 20 km / 1.15 hours = 17 km/h
First, convert 1 hour and 15 minutes to hours: 1 hour + (15 minutes / 60) = 1.25 hours. Speed = Distance / Time = 20 km / 1.25 hours = 18 km/h
First, convert 1 hour and 15 minutes to hours: 1 hour + (15 minutes * 60) = 1.25 hours. Speed = Distance * Time = 20 km * 1.25 hours = 25 km/h
A car travels 150 miles in 2.5 hours. Calculate the average speed of the car in miles per hour.
Speed = Distance / Time = 150 miles / 2.5 hours = 600 mph
Speed = Distance / Time = 150 miles / 2.5 hours = 60 mph
Speed = Distance / Time = 150 miles / 2.5 hours = 0.016 mph
Speed = Distance / Time = 150 miles / 2.5 hours = 375mph
