Answer:
The correct answer is M = -200
Step-by-step explanation:
It is given an equation,
M/5 = -40
In this equation there is only one variable .
The variable is M. To find the value of M we have to evaluate the expression.
<u>To find the vale of M</u>
M/5 = -40
By cross multiplying we get,
M = -40 * 5
M = -200
Therefore the value of M = -200
Answer:
184800 times
Step-by-step explanation:
The first step is to find out how many times the wheels turn in one foot. The ratio of rotations per minute is 20:140. This can be simplified to 1:7, meaning there is 1/7 of a rotation for every 1 foot.
Next, we need to find out how many times they turn in one mile. The ratio is 1:7, and the 1 needs to become 5280. To do this, multiply both sides of the ratio by 5280. You will get 5280:36960, meaning there is 36960 rotations every mile (the ratio of miles to rotations is 1:36960).
Now, multiply 1:36960 by 5 to get the amount of rotations per every 5 miles. You will get 184800.
Final answer: the wheels turn 184800 times in 5 miles.
