Solve the answer and show your work so a 747 boejing jet flying from new york city to hong kong can carry about 160 passengers. the plane travels at an average speed of 715 mph. the distance from new york to hong kong is 8,054 miles. how long is the flight from new york to hong kong? choose the equation that would solve this problem is it a. 715 divided by 8,054 or b. 8,054 x 715 or c. 8,054 divided by 715 or d. 715 x 160

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
