Final answer:
To convert a giraffe's speed from 15 meters per second to miles per hour, multiply by the conversion factor to get feet per second and then convert to miles per hour. After calculation, the speed is approximately 33 mph.
Step-by-step explanation:
To find the speed of a giraffe in miles per hour when its speed is known to be 15 meters per second, we must perform unit conversions using the provided equivalencies.Firstly, convert meters to feet by multiplying 15 m/s by the conversion factor 3.28 ft/m. This gives us 49.2 ft/sNext, we need to convert feet per second to miles per hour. To do this, we multiply by the number of seconds in an hour (3600 seconds) and divide by the number of feet in a mile (5280 feet), which gives us the formula: speed in mi/hr = (49.2 ft/s) × (3600 s/hr) / (5280 ft/mi)After performing the calculations,
we get that the speed of the giraffe is approximately 33.5 mi/hr. Therefore, the closest answer would be option A, which is 33 mphTo find the speed of a giraffe in miles per hour, we need to convert the given speed in meters per second to miles per hour.Given: 1 mi = 5,280 ft; 1 m ≈ 3.28 ftFirst, let's convert the speed of the giraffe from meters per second to feet per second. We know that 1 meter is approximately equal to 3.28 feet, so:15 m/s * 3.28 ft/m = 49.2 ft/sNext, let's convert the speed from feet per second to miles per hour. We know that 1 mile is equal to 5,280 feet, so:49.2 ft/s * 1 mi/5280 ft * 3600 s/1 h = 66 mi/hTherefore, the speed of the giraffe is approximately 66 miles per hour.The converted speed of a giraffe that runs approximately 15 meters per second is 33 mph (miles per hour).
