The distance between David's home and the airport is 210 miles.
<h3>Distance traveled after 1 hour</h3>
let the distance traveled after first 1 hour = y
distance/speed = time
after 1 hour his speed = (35 + 15) = 50 mph
total time after 1 hour and 30 mins = 1.5 hr
y/50 + 1.5 = y/35
multiply through by350
7y + 525 = 10y
3y = 525
y = 525/3
y = 175 miles
In the first 1 hour, at 35 mph, distance covered = 35 miles
Distance from his home to airport = 175 miles + 35 miles = 210 miles
Thus, the distance between David's home and the airport is 210 miles.

Given:
The volume of a prism with equilateral triangular cross-section is 270cm³.
Length of the prism =
cm
To find:
The length of the side of the equilateral triangular cross-section.
Solution:
Formulae used:
Area of an equilateral triangle is

Where a is the side length of equilateral triangle.
Volume of prism is

Where, B is base area and h is the height of the triangular prism.
Cross section of the prism is an equilateral triangular so the base area of the prism is
sq. cm.
The volume of the prism is




Divide both sides by 7.5.




It takes only positive value because the side cannot be negative.
Therefore, the length of the side of the equilateral triangular cross-section is 6 cm.
2 hours costs 6 dollars is the only statements that is true
--
simply add 3.00 to 3.00 because its 2 hours
or if it was half an hour simply add 1.50 because half of 3.00 is 1.50
