Zack’s car travels 30.2 miles in 2/3 of an hour. What is the average speed, in miles per hour, of the car?

Step-by-step explanation:

30.2 miles / 2/3 hour

This is saying 30.2 divided by 2/3. When you divide by a fraction you have to multiply by the inverse

30.2 x 3/2

90.6 / 2

45.3 miles per hour

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
