The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)
The appropriate customary unit is calculated as:
1 km = 0.62 miles
153 km = x
Cross Multiply
x = 153 × 0.62 miles
94.86 miles
Therefore, the appropriate customary unit is 94.86 miles per hour
