Michael cycled a distance of miles in hours. What is his cycling unit rate in miles per hour?Michael cycled a distance of miles
notka56 [123]

Answer:

The number of miles/the number of hours

Step-by-step explanation:

If the number of hours is not equal to 1, multiply the numerator and denominator by the inverse of the number of hours.

For example, 10 (miles)/2 (hours)

The inverse of 2 is 1/2, so --> the new equation is 10/2 * 1/2 / 1/2 or

10* 1/2 and 2 * 1/2

When multiplied out, this leads to 5/1 or 5 miles per hour

Because of the 30°-60°-90° angles theorem, The side opposite 90° is double the side opposite 30°, which means that x=32.
