What is the speed of a snake that moves 20 m in 5 seconds ?
1 answer:
The speed of the snake is 8.95 miles per hour.
Step-by-step explanation:
Step 1:
The snake travels at a speed of 20 meters in 5 seconds.
We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.
The distance covered in 1 second
So the snake is moving at a distance of 4 meters per second.
Step 2:
To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.
So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.
4 meters per second miles per hour.
Rounding this off, we get the speed of the snake as 8.95 miles per hour.

Hello,
Rational numbers are numbers that can be represented by fractions that consist of integers.
In this case, B. -7/3 is already a fraction that consists of integers, so it is a rational number.
C. square 3 is =
= 9, which can be represented by 9/1, so it is also a rational number.
A and D are incorrect as they cannot be represented by fractions that consist of integers.
The answers are B and C.
Hope this helps!
