Answer:
10m
Step-by-step explanation:
Area of a triangle: 
bh
where 'b' = base and 'h' = height
plug in known values: 20 = 
cross-multiply: 4b = 40
b = 10
Answer:
B) 10 m
Step-by-step explanation:
Area is 20 and Height is 4
Ok so
AREA of a triangle is =1/2Base Times Height
work back
Area=20
Height=4
b=Base
20=1/2b*4
Simplify both sides of the equation.
20=2b
Flip equation
2b=20
Divide both sides by 2
b=10
Base=10 m

Answer:
$578.30
Step-by-step explanation:
537.95(.075)= 40.35
$40.35 + $537.95 = $578.30
We can see that for every 1 hour he increases 10 miles in his distance, so we can say it's constant, he started at 0 and increased 10 miles per hour.
