Answer 1

Step-by-step explanation:

1.

Let the required length of the model of ship = x cm.

Since, more the length of the ship, more would be length of its mast.

∴ Length in model ship and in actual ship are in direct proportion.

=> (x/30) = (8/12)

=> 12x = 240

=> x = 20

∴ Length of the actual ship = 20 m.

(2)

(i)

364 km = 7 hours

1 km = (7/364)

884 km = (7/364) * 884

              = 17 hours

Therefore, the time it takes = 17 hours.

(ii)

4 hours 20 minutes = 260 min.

Now,

= (364 * 260)/7

= 13520 km

Hope it helps!
