Questions & Step-by-Step Solutions
If the length of a river is 240 km and it flows at an average speed of 4 km/h, how long will it take for the river to flow from its source to the mouth? (2021)
Step 1: Identify the total length of the river, which is 240 km.
Step 2: Identify the average speed of the river, which is 4 km/h.
Step 3: Use the formula for time, which is Time = Distance / Speed.
Step 4: Plug in the values: Time = 240 km / 4 km/h.
Step 5: Calculate the time: 240 divided by 4 equals 60.
Step 6: Conclude that it will take 60 hours for the river to flow from its source to the mouth.
Distance, Speed, and Time Relationship – This question tests the understanding of the fundamental relationship between distance, speed, and time, which is expressed by the formula: Time = Distance / Speed.
