Answer:
A
Step-by-step explanation:
<em>Units of Lenght :</em>
- <em>Km</em>
- <em>Hm</em>
- <em>Dam</em>
- <em>m</em>
- <em>dm</em>
- <em>cm</em>
- <em>mm</em>
- <em> ÷10 for each step ↑</em>
- <em> x10 for each step ↓</em>
7200 km = 7200.1000 m
1 h = 60 minutes
every minute has 60 s.
1 h = 60 x 60 s
km/h =
m/s
2.1000 = 2000
Hope this helps ^-^

slope (m ) = , y - 1 =
( x - 2)
The equation of a line in ' point- slope form 'is
y - b = m (x - a)( m is the slope and (a , b ) a point on the line )
To calculate m use the ' gradient formula'
m = (y₂ - y₁ )/(x₂ - x₁ )
let (x₁, y₁ ) = (2 , 1) and (x₂, y₂ ) = (14 , 31) ← values chosen from table
m = (31 - 1 )/(14 - 2 ) = =
equation in point- slope form using m = and (a,b )= (2 , 1)
y - 1 = ( x - 2)
