<u>Statement</u><u>:</u>
A softball field is a square with sides of length 60 feet.
<u>To </u><u>find</u><u> </u><u>out:</u>
The shortest distance between the first base and third base, i.e., the displacement
<u>Solution:</u>
- Let us consider 1st base as A, Home Plate as B and 3rd base as C.
- AB = 60 ft
- BC = 60 ft.
- To find out the shortest distance between the first base and third base we have to find out the value of AC.
- In right triangle ABC,
- (AB)² + (BC)² = (AC)² [By Pythagoras Theorem]
- or, (AC)² = (60 ft)² + (60 ft)²
- or, (AC)² = 3600 ft² + 3600 ft²
- or, (AC)² = 7200 ft²
- or, AC = √7200 ft
- So, the shortest distance will be √7200 ft.
<u>Answer</u><u>:</u>
<u>D. √7200 ft</u>

Answer:
In 15 hrs they will make 2100 bagels
Step-by-step explanation:
Step one :
Given that it takes
2hrs to make 280 bagel
Hence in
15 hrs they will make x bagels
by cross multiplication
x= (280*15)/2
x= 4200/2=2100 bagels
x= 2100
