Step-by-step explanation:
1 km = 1000 m
(hence the term "kilo" which means 1000).
so. he runs 1000 m at the rate of 3 minutes per km, that means 3 minutes per 1000 m.
now, we can see the solution already with our eyes.
but let's do it formally :
the rate or ratio between time and distance must be the same for the same speed.
so,
3 min / 1000 m = x min / 500 m
500 m × 3 min / 1000 m = x min
1/2 × 3 min = x min
3/2 = 1.5 min = x min
so, it takes him 1.5 minutes (90 seconds) to run 500 m.
Answer: unit rate = 1 / 5 = 0.2 inches per day
Step-by-step explanation:
The unit rate is the ratio that describes how one quantity changes as the other changes.You can find a unit rate from a graph the same way you find the slope.
1. Choose two points on the graph to find the slope
- (0,0) and (5,1)
x₁ y₁ x₂ y₂
2. Slope = y₂ - y₁ / x₂ - x₁ (This is essentially the change in y-coordinates divided by the change in x-coordinates.
unit rate = y₂ - y₁ / x₂ - x₁
unit rate = 1 - 0 / 5 - 0
unit rate = 1 / 5 = 0.2 inches per day
V = 180 cm3
l = 10 cm
w = 4 cm
h = ?
V=lwh, so to get h, divide equation by lw, to get h=V/(lw).
h = 180/(10*4) = 4.5 cm
You have to do the math right to get this right. so just add then multiply add them the subtract
