Answer:a. Speed in Kilometers per Minute 1. Convert Hours to Minutes We know that 1 hour has 60 minutes. Therefore, to convert the speed from kilometers per hour to kilometers per minute, we divide the speed in kilometers per hour by 60: 2. Calculation Applying the formula, we get: Therefore, the speed of the zipline is 1.5 kilometers per minute. b. Round Trip Time 1. Calculate the Total Distance The dual zipline has a total distance of 840 meters * 2 = 1680 meters. 2. Convert Meters to Kilometers Since the speed is in kilometers per minute, we need to convert the distance to kilometers. We know that 1 kilometer is equal to 1000 meters. Therefore: 3. Calculate the Round Trip Time We can calculate the time taken for the round trip by dividing the total distance by the speed: Applying the values, we get: Therefore, it would take 1.12 minutes to complete a round trip on this zipline.
Answer:a or bStep-by-step explanation:a. To find the speed in kilometers per minute, we can convert the speed from kilometers per hour to kilometers per minute. Given: - Speed = 90 kilometers per hour To convert kilometers per hour to kilometers per minute, we can use the conversion factor:1 hour = 60 minutes So, the speed in kilometers per minute would be: b. To calculate how long it would take for a round trip on the dual zipline, we need to consider the total distance for the round trip. Given: - Length of one zipline = 840 meters- Dual zipline (round trip) = 840 meters * 2 Firstly, let's convert the total distance to kilometers: Next, we can calculate the time it would take for the round trip at a speed of 1.5 km/min: Let's calculate the time for the round trip.The calculations have been completed. Here are the results: a. The speed of the zipline in kilometers per minute is kilometers per minute. b. The time it would take for a round trip on the dual zipline is approximately minutes.
