Questions & Step-by-Step Solutions
If the length of a river is 120 km and it flows at an average speed of 5 km/h, how long will it take for the river to flow from its source to its mouth? (2021)
Step 1: Identify the total length of the river, which is 120 km.
Step 2: Identify the average speed of the river, which is 5 km/h.
Step 3: Use the formula for time, which is Time = Distance / Speed.
Step 4: Plug in the values: Time = 120 km / 5 km/h.
Step 5: Calculate the result: 120 divided by 5 equals 24.
Step 6: Conclude that it will take 24 hours for the river to flow from its source to its mouth.
Distance, Speed, and Time Relationship – This question tests the understanding of the relationship between distance, speed, and time, specifically using the formula Time = Distance / Speed.
