Answer:
9.8 km/h
Step-by-step explanation:
Since there are 60 minutes in an hour, we can find his speed in km/h by multiplying 4.9 by 2.
4.9(2)
= 9.8
This means that he will travel 9.8 km in 60 minutes (1 hour).
So, his average speed is 9.8 km/h
Answer:
V(x) = l*w*x - 2*l*x² - 2*w*x² + 4*x³
Step-by-step explanation:
The volume of any box is:
a * b * h where a is the length, b is the wide and h is the height
Assuming we have cardboard of dimensions: l * w
l - 2*x will be length of the box and
w - 2*x will be wide of the box
h = x the height, then:
V(x) = ( l - 2*x ) * ( w - 2*x ) * x
V(x) = [ ( l*w - 2*l*x - 2*w*x + 4*x² ] * x
V(x) = l*w*x - 2*l*x² - 2*w*x² + 4*x³
