Express each ratio as a unit rate.Round to the nearest tenth, if necesary.
A: 400 feet in 52.4 seconds
B: 184 meters in 38 seconds
To express each ratio as a unit rate, we need to convert the given quantities into a ratio of distance to time with a consistent unit. In both cases, we have a distance (feet or meters) and a time (seconds) provided.
A: 400 feet in 52.4 seconds
To express this as a unit rate, we divide the distance by the time:
Unit rate = Distance / Time
Unit rate = 400 feet / 52.4 seconds ≈ 7.633 feet/second (rounded to the nearest tenth)
Therefore, the unit rate of 400 feet in 52.4 seconds is approximately 7.6 feet/second.
B: 184 meters in 38 seconds
To express this as a unit rate, we divide the distance by the time:
Unit rate = Distance / Time
Unit rate = 184 meters / 38 seconds ≈ 4.842 meters/second (rounded to the nearest tenth)
Therefore, the unit rate of 184 meters in 38 seconds is approximately 4.8 meters/second.
400/52.4 = 7.6 ft/s
184/38 = 4.8 m/s
