The equation of the graph is C.
We use the formula : Displacement = Average Velocity * Time ;
17 = ( v + 8 ) * t ;
1 = ( v - 8 ) * t ;
where v = the velocity of the boat; t is the time from expression " ... in the same amount of the time he rows ....."
Then 17 / 1 = (v + 8) / ( v - 8 ) ;
v + 8 = 17( v - 8 );
v + 8 = 17v - 136 ;
144 = 16v ;
v = 144 / 16;
v = 9 mph ;
18 = 9 * x ;
x = 18 / 9 ;
x = 2 hours ;
The answer is 2 hours ;
0.00373134328
I think you can round that but I think that's the answer.
Answer:
Step-by-step explanation:
Answer: 40%
Divide 24 / 60 =0.4
4z+6.1≥43.7-4z
add 4z on both sides - 8z+6.1≥43.7
subtract 6.1 on both sides - 8z≥37.6
divide by 8 on both sides - v≥4.7
