Answer:
2km/m
Step-by-step explanation:
6 laps = 10km
(because 3 x 2 = 6 and double 5km as well)
Distance divide time = speed
20 mins divided by 10km = 2km per minute
Answer:
448 in²
Step-by-step explanation:
Larger cube:
6s² - overlapping square
6(8²) - 4²
6×64 - 4²
384 - 16
368
Smaller cube:
5(4²)
5×16
80
Area = 368 + 80
448 in²
Let x represent the width of the rectangle.
We know 2x=length
Perimeter of a rectangle is 2(length)+2(width)
So we can make an equation for the perimeter of this particular rectangle.
2(2x)+2(x)=60
4x+2x=60
6x=60
x=10.
Since the width is equal to x, we know that the width of this rectangle is 10 m.
And, the length is twice of the width.
10*2=20
Therefore, the length of the rectangle is 20 meters.
