Answer:
(X+5)(x^2-5x+25)
Step-by-step explanation:
1kg is 2.20462 pounds
So 4kgs are 8.81849
Divided by $16 would equal 0.551155625
Therefore Each pound will cost 0.551155625
1.679 kg * (40 min)/(kg) + 20 min = 67.16 min + 20 min = 87.16 min
Your answer would be 5 hours. Because total time divided by rate is the time it took to travel that distance. 250mi/50mph=5hours. Hope this helps.
