The rate would show 0.5 equals 37 so that will be your answer
Answer:
His average speed for the rest of the journey was of 48mph.
Step-by-step explanation:
We use the following relation to solve this question:

In which v is the velocity, d is the distance and t is the time.
First 32 miles at an average speed of 64mph.
So the time for these 32 miles is:




Rest of the trip:
200 - 32 = 168 miles in 4 - 0.5 = 3.5 hours. So the average speed is of:

His average speed for the rest of the journey was of 48mph.
Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Step-by-step explanation:
No 1/5 = 1/5 5/5 = 1 and 5/1= 5
