Questions & Step-by-Step Solutions
A radar system can detect objects up to 200 km away. If it scans at a speed of 20 km/h, how long will it take to complete a full scan? (2022)
Step 1: Identify the maximum distance the radar can detect, which is 200 km.
Step 2: Identify the speed at which the radar scans, which is 20 km/h.
Step 3: Use the formula for time, which is Time = Distance / Speed.
Step 4: Plug in the values: Time = 200 km / 20 km/h.
Step 5: Calculate the time: 200 divided by 20 equals 10.
Step 6: Conclude that it will take 10 hours to complete a full scan.
Distance, Speed, and Time Relationship – Understanding the formula that relates distance, speed, and time, specifically how to calculate time taken for a journey based on these variables.
