Answer: Each lap that Marshall runs has 452.16 yards

Step-by-step explanation:

Because the lap is circular, we know that the distance from the center of the track to any point of the path must be the same.

We know that he walkerd 72 yards, from the center to the path, se we know that the path is a cirlce of radius equal to 72 yards.

The perimeter of a circle is equal to P = 2*pi*r

where pi = 3.14

so we have that the perimeter of the track is 2*3.14*72 yards = 452.16 yards.

So each lap that Marshall runs has 452.16 yards

Greg swam 4 kilometers against the current in the same amount of time it took him to swim 16 kilometers with the current. The ra
ad-work [718]

Answer:

5 kmph

Step-by-step explanation:

Given: Greg swam 4 kilometers against the current.

            Greg swam 16 kilometers with the current.

            Rate of the current was 3kmph.

Lets assume the speed of greg swimming with no current be "x".

∴ Speed of swimming against current= (x-3)\ kmph

   Speed of swimming with current= (x+3)\ kmph

As given, it took same amount of time to swim both with current and against current.

∴ Forming an equation to find the value of x, which is speed of greg swimming with no current.

We know, Time= \frac{Distance}{Speed}

⇒ \frac{4}{(x-3)} = \frac{16}{(x+3)}

Multiplying both side by (x+3) and (x-3)

⇒4\times (x+3)= 16\times (x-3)

Using distributive property of multiplication.

⇒ 4x+12= 16x-48

Subtracting both side by 4x and adding by 48.

⇒60= 12x

Dividing both side by 12

⇒x= \frac{60}{12} = 5\ kmph

Hence, Greg can swim at the rate of 5kmph with no current.

zhannawk [14.2K]
Percent increase
find increase
then divided that by original

562157+531285=30872=increase

now put that over original
30872/531285=0.05810817/1
percent means partst out of 100
make bottom number 100
0.05810817/1 times 100/100=5.810817/100=5.810817%
