Answer:
The Car.
Step-by-step explanation:
We need to find the unit rate for each vehicle to figure out who is traveling faster or slower.
Car: 600/20 = 30 ft per second
Motorcycle: 300/12 = 25 ft per second
So, the Car is faster
600ft/20sec = 30ft per sec 300ft/12sec = 25 fr per sec This means the car is faster by 5 seconds

From the question we are told that:
Diameter
Radius
Generally the equation for Circumference of a circle is mathematically given by
The expression is equivalent to r^(m-n)
Let x units be the length of the shortest side of the triangle. Perimeter of triangle = 2(x + 1) +x = 3x + 2 Perimeter of square = 4(x - 2) = 4x - 8 Equating the two expressions for perimeters, we get: 3x + 2 = 4x - 8 The solution is: x = 10 The answer is 10 units.
Answer:
D. 77 + 8
