Answer : The Susana swam the fastest.
Step-by-step explanation :
Speed : It is defined as the distance traveled per unit time.
Formula used :

First we have to determine speed of the following persons.
<u>For Tawni :</u>
Distance = 50 m
Time = 40.8 s

The speed of Tawni is, 1.225 m/s
<u>For Pepita :</u>
Distance = 100 m
Time = 60.2 s

The speed of Pepita is, 1.661 m/s
<u>For Susana :</u>
Distance = 200 m
Time = 112.4 s

The speed of Susana is, 1.779 m/s
From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.
Thus, Susana swam the fastest.
The two expressions are not equivalent, you figure this out by solving both problems individually and seeing if the answer is the same as the other
22) D. 5 miles
23) E
24) C. 4:30
3 1/4
I think, I’m not sure
Total mass of the atoms=number of atoms * weight of an atom
Total mass of the atoms=(4.02*10²³)*(1.67*10⁻²⁴)=(4.02*1.67)*(10²³⁻²⁴)=
=6.7134*10⁻¹
Answer: 0.67 grams, because (4.02*1.67)*(10²³*10⁻²⁴)=6.7134*10⁻¹
