Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.
Given: Given that a citizen have 97 silver coins.
To find : Here we need to find that how many bronze coins would it take to equal this amount.
Solution: We know, 1 silver coin=10 bronze coin
So, 97 silver coin=10×97 bronze coin
=970 bronze coin
Therefore, 970 bronze coins would it take to equal this amount.

Answer:

along the direction 68.19° from north.
Step-by-step explanation:
Given,
- speed of the boat, u= 2 miles/hour along north
- speed of the river, v= 5 miles/ hour along east
Since, north and east are perpendicular to each other, so we can write the resultant velocity in vector form as,

Hence, the magnitude of resultant velocity can be written as



Hence, the magnitude of resultant vector is \sqrt{29} moles/hour.
And the direction of the boat can be given by,



= 68.19°
Hence, the resultant velocity of boat is
miles/hour along the direction making an angle 68.19° with the north.
