Answer:
it's d it makes alot of sense and ik it's right
Answer:
<h2>The answer is 7.47</h2>
Step-by-step explanation:
In this problem we are going find the natural logarithmic of the numbers involved and solve for x

from tables
<h3> ln 65= 4.17</h3>

taking the exponents of both sides we have

D = vt
Distance traveled by train
d = 55t
Distance traveled by plane
d = 285t
Total distance
d = 1020
So, you do:
distance traveled by plane + distance traveled by train = total distance
(55t) + (285t) = 1020
Solve for t
t = 3 hours
t is the time traveled by each so 3 hrs traveled by train and 3 hrs traveled by plane
Total time = 3 + 3 = 6 hours
1 kg = 1,000,000 mg
55,000 mg = 55,000/1,000,000 = 0.055 kg
0.055 kg < 2 kg
so 55,000 mg < 2 kg
