Answer:
Apolo Ohno skated about 26.84 miles per hour
Step-by-step explanation:
Given:
Apolo Ohno won a gold medal by skating about 12 m/s
We need to find 12 m/s in miles per hour
1 hour consist of 3600 seconds
12 m/h = ![12\times3600 =43200\ meter \ per \ hour](https://tex.z-dn.net/?f=12%5Ctimes3600%20%3D43200%5C%20meter%20%5C%20per%20%5C%20hour)
1 mile = 1609.344 meter
how many miles Ohno skated = 43200 meter per hour
By using Unitary Method we get
Miles Apolo Ohno Skated =![\frac{43200}{1609.344}= 26.84323](https://tex.z-dn.net/?f=%5Cfrac%7B43200%7D%7B1609.344%7D%3D%2026.84323)
Rounding to nearest hundred we get
Apolo Ohno Skated about 26.84 miles per hour
The answer would be 7/24.
