5 2/3 divided by 2 2/3 = 17/3 divided by 8/3 = 17/8 = 2 1/8 miles per hour
2 2/3 divided by 5 2/3 = 8/3 divided by 17/3 = 8/17 hours per mile
Answer:
the expression would be 3(7+s)
Answer: 50 yards by 25 yards
Step-by-step explanation:
rink is also a rectangle
perimeter= 150 yards
length= 2x
width=x
the perimeter of rink is:
p=2(length + width)
150=2(2x + x)
150= 2(3x)
150= 6x
x=150 / 6
x=25
so width is 25 yards and length is twice the width which is 2x
length= 2× 25
length= 50 yards
so the dimension is 50 yards by 25 yards
