Answer:
10 hours
Step-by-step explanation:
Given:
Average speed of submarine = 10 mph
Speed of carrier in the opposite direction = 20 mph
Distance between the submarine and carrier = 300 mi
To find:
The time taken so that the distance between them is 300 mi ?
Solution:
The relative speed when they are traveling in opposite direction = 10+20 = 30 mph
Formula:
So, the answer is <em>10 hours</em>.
Answer:
y < -11
Step-by-step explanation:
First you would subtract 4y from both sides, leaving you with 4y + 2 < -22. Then you would subtract 2 from both sides leaving you with 4y < -44 because when you subtract 2 from -22 you have to change the 2 to negative and the subtraction to addition. So, then you divide 4 on both sides leaving you with... y < -11, because if you divided -44 by 4 you get 11, but its negative so, it would be -11.
