Hey there! I'm happy to help!
28(5280)=147840 feet per hour.
There are 60 minutes in an hour. To find out how many feet Bolt runs in a second we divide by 60.
147840/60=2464
And we divide by sixty again to get to seconds.
2464/60=41 1/15 feet per second.
Have a wonderful day! :D
Answer:
NW = 15.6 cm
Step-by-step explanation:
If ΔLMN ~ ΔNWR then:





Find NW by using Pythagoras' Theorem:

(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
- a = RN = 6 cm
- b = RW = 14.4 cm
- c = NW
Substituting the given values into the formula and solving for NW:




Part 1: should be C. Because the question said 1.2 added to a number.
Part 2:16.8
