In the left hand side, you're multiplying 7.8 by 3.6\times 1

In the right hand side, you're multiplying again 7.8 by a mysterious number.

So, the unknown number must be 3.6\times 1

Every number remains unchanged when multiplied by 1, so the answer is 3.6

Answer:

The distance between the docks & island is 44.07 km.

Time taken by bot to reach the island = 7 hr

We know that the distance is given by

Distance = Speed × Time

Put all the values in above equation we get

D = 6.3 × 7

D = 44.07 km

Therefore the distance between the docks & island is 44.07 km.
