Sure! Here are a few example problems involving speed, distance, and time, along with their solutions.
Problem 1:
A car travels at a speed of 60 km/h for 2 hours. How far does the car travel?
Solution:
- Given:
- Speed (S) = 60 km/h
- Time (T) = 2 hours
- Using the formula: Distance (D) = Speed (S) × Time (T)
D=60 km/h×2 h=120 kmAnswer: The car travels 120 kilometers.
Problem 2:
A runner covers a distance of 15 kilometers in 3 hours. What is the speed of the runner?
Solution:
- Given:
- Distance (D) = 15 km
- Time (T) = 3 hours
- Using the formula: Speed (S) = Distance (D) ÷ Time (T)
S=15 km3 h=5 km/hAnswer: The runner’s speed is 5 km/h.
Problem 3:
A plane travels 900 kilometers in 3 hours. What is the speed of the plane?
Solution:
- Given:
- Distance (D) = 900 km
- Time (T) = 3 hours
- Using the formula: Speed (S) = Distance (D) ÷ Time (T)
S=900 km3 h=300 km/hAnswer: The speed of the plane is 300 km/h.
Problem 4:
A cyclist is traveling at 12 km/h. How long will it take to travel 72 kilometers?
Solution:
- Given:
- Speed (S) = 12 km/h
- Distance (D) = 72 km
- Using the formula: Time (T) = Distance (D) ÷ Speed (S)
T=72 km12 km/h=6 hoursAnswer: It will take the cyclist 6 hours to travel 72 kilometers.
Problem 5:
A train travels 540 kilometers in 9 hours. What is its average speed?
Solution:
- Given:
- Distance (D) = 540 km
- Time (T) = 9 hours
- Using the formula: Speed (S) = Distance (D) ÷ Time (T)
S=540 km9 h=60 km/hAnswer: The average speed of the train is 60 km/h.
