It took Andre and Lin 1.5 hours for them to meet.
Speed is the ratio of distance travelled to total time taken. Speed is given by:
Speed = distance/time
Let d₁ represent the distance covered by Andre at time t and d₂ represent the distance covered by Lin at time t.
Hence:
5 = d₁/t
d₁ = 5t
3 = d₂/t
d₂ = 3t
Andre and Lin are 12 miles apart, hence:
d₁ + d₂ = 12
5t + 3t = 12
8t = 12
t = 1.5 hours
It took Andre and Lin 1.5 hours for them to meet.

Answer:
<h2>(3, -2)</h2>
Step-by-step explanation:
Answer is 4,320 dollars because once you do 5*86400 you move the decimal to the left two times since each ml is 0.05. Giving you $4,320
It is very simple you minus 9 from 7. 9-7=2. So Alberto's birthday is on the 2nd.
Answer:
the distance between the other two subs is 207 meters
Step-by-step explanation:
Lara's radar on her submarine detects two other subs nearby. The first sub is 360m away, the second sub is 250m, and the angle between them is 34
Two sides and included angle is given
to find the opposite side of the angle we use cosine formula
b=250 , c=360 and angle A is 34 degrees
take square root on both sides to remove square
the distance between the other two subs is 207 meters
