Answer:
Frank
Step-by-step explanation:
First let's start by calculating the speed of each runner.
Let's use feet per second
Frank's speed is already given in feet per second: 14 feet/second
We are given that Jake runs 382 feet in 38 seconds. To bring this down to feet/second we need to divide both numbers by 38.
382/38=10.05 feet/second (about)
We are given that Will runs 1 mile in 394 seconds. 1 mile is equivalent to 5280 feet. Now we divide both numbers by 394 to bring it down to feet/second.
5280/394=13.401 feet/second (about)
We are given that Ron runs 555 feet in 1 minute. 1 minute is equivalent to 60 seconds. Now we divide both numbers by 60 to bring it down to feet/second.
555/60=9.25 feet/second
After comparing all the speeds, we can conclude that Frank runs the fastest

Answer:
1/2
Step-by-step explanation:
Answer:
A = 20 degree
B = 160 degree
C = 160 degree
D = 20 degree
Step-by-step explanation:
If the measure of angle C is eight timeseight times the measure of angle A
That means C = 8A
But According to the question, angles A and D have the same measure as well as angles C and B.
That is, B = 8A and D = A
If A + B + C + D = 360
Let us substitute for B, C and D
A + 8A + 8A + A = 360
18A = 360
A = 360/18 = 20
Therefore
A = 20 degree
B = 8 × 20 = 160 degree
C = 8× 20 = 160 degree
D = 20 degree
