Answer:
4.41/ 3 = 1.47 each
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Answer:
a = 324
Step-by-step explanation:
9=1/27 a -3
value of a = ?
9=(1/27) a -3
9 + 3 = (1/27) a
12 = (1/27) a
12 x 27 = a
a = 324
Consider this option:
1. if to re-write the condition, it is given: total time t=8 hours; upstream=downstream=6 miles; V_boat=4 m/h., V_current=V=?
2. note, that total time=time_upstream+time_downstream, where time_upstream=6miles/(V_boat-V) and time_downstream=6miles/(V_boat+V). Using this it is possible to make up and solve the following equation:
answer: √10
P.S. the roots of the equation are √10 and (-√10), only positive values is needed for V.
