Answer:
45 miles
Step-by-step explanation:
Since she drives a total of 3 hours traveling 15 miles each hour you just multiply 15 times 3
How many degrees is the tire turning every second?
Enter your answer in the box.
Answer:
180 degrees per second.
Step-by-step explanation:
We have been given a graph that shows the distance covered by a tire or angular velocity of a tire with respect to the number of seconds (x).
Since we know that a tire is a circle and the measure of all the angles of a circle equals to 360 degrees.
We can see from our given graph that the tire completes one rotation in 2 seconds (2.5-0.5), so the distance covered by tire in two seconds will be 360 degrees. This means that the tire turns 360 degrees in each 2 seconds.
As we are asked to find the degree change by tire per second so we will find the unit rate such that we will have 1 in our denominator. By dividing our numerator and denominator by 2 we will get,
Therefore, the tire is turning 180 degrees per second.
It takes 2 seconds for the tire to make a full revolution. This is evident from the plot - the curve has a period of length 2.
A full revolution of the tire is a turn of 360 degrees.
So the tire turns at a rate of (360 degrees)/(2 seconds) = 180 degrees/second.
