Step-by-step explanation:
162 kilometers = 162000 meters
1 hour = 3600 seconds.
162,000 meters/3600 seconds=45 meters/second=45 m/s
45*10=450
Answer:
Step-by-step explanation:
Let:
P - perimeter
l - length
w - width
We know:
P = 118 m
l = 2w - 7
<h3>Rectangle perimeter's formula: P = 2l + 2w</h3>
We replace the length with 2w - 7.
P = 2×(2w - 7) + 2w
118 = 4w - 14 + 2w
118 = 6w - 14
6w = 118 + 14
6w = 132
w = 22 meters
