Answer:
t_a = 7 s
t_w = 5 s
Step-by-step explanation:
Given:
- The average speed in air v_a = 16 m/s
- The average speed in water v_w = 3 m/s
- The total distance D = 127 m
- The total time T = 12 s
Find:
How long did the stone fall in air and how long did it fall in the water?
Solution:
- Lets time taken by stone to drop through air as t_a = t_a.
- The time taken in water would be t_w = (12 - t_a)
- The total distance covered can be calculated as:
                             D = v_a*t_a+ v_w*(12 - t_a)
                             127 = 16*t_a + 3*(12 - t_a)
Simplify and solve for t:
                             91 = 16*t_a - 3t_a
                             13*t_a = 91
                             t_a = 7 s
                             t_w = 5 s
                             
 
        
             
        
        
        
Answer:
Step-by-step explanation:
(2b+-7)+5(b+-3)
Multiply 5 throughout the second parentheses
 (2b-7)+(5b-15)
Add 2b and 5b
7b-7-15
Subtract -7 and -15
7b-22
