The relationship between speed, distance, and time is given by:

Speed = Distance ÷ Time

From this formula, we can derive:

• Distance = Speed × Time
• Time = Distance ÷ Speed

Examples:

• A car travels 120 km in 2 hours. Speed = 120 ÷ 2 = 60 km/h
• A train travels at 80 mph for 3 hours. Distance = 80 × 3 = 240 miles
• How long to travel 150 km at 50 km/h? Time = 150 ÷ 50 = 3 hours
