Answer:
B. 4
Step-by-step explanation:
The figure is a triangle 4 units wide and 2 units high. Its area is ...
A = (1/2)bh = (1/2)(4)(2)
A = 4 . . . . square units
Remark
This may be a little confusing, but because they are travelling in opposite directions, the distances add when you want to get how far apart they are.
d1 + d2 = 1541
Equation
Let the time this happens = t
d1 = 323*t
d2 = 347*t
323*t + 347*t = 1541 Combine like terms on the left.
670t = 1541 Divide by 670
t = 1541/670
t = 2.3 hours pass before the distance of 1541 miles are between the two planes. You might need the answer to be 2 hours 18 minutes.
