Answer:
x = 15 cm
Step-by-step explanation:
All the ratio of corresponding sides should be equal
10 corresponds to x
16 corresponds to 24
12 corresponds to 18
<em>Finding the ratio of the known pairs:</em>
<em>Similarly 10 is to x should be 2 is to 3. Finding x:</em>
So x = 15.
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.
