Answer:
2
Step-by-step explanation:
If you sketch the path of the boat, you will form a right triangle towards the port. The distance from the port to the present position is the hypotenuse since it is opposite from the right angle formed by the 12 miles north and 5 miles east movement. Since it is a right triangle, use the Pythagorean Theorem to solve the hypotenuse.
Solution:
h² = o² + a²
h² = 12² + 5²
h² = 144 + 25
h² = 169
√h² = √169
h= 13
The present distance of the boat from the port is 13 miles.

Answer:
1 and a half hours < 100 mins
Step-by-step explanation:
1 and a half hours is equal to :
1 hour = 60 mins
half hour = 30 mins
60 + 30 = 90 mins
90 min is less than 100 mins
Therefore / ∴ :
1 and a half hours < 100 mins
1.12=1 12/100=1 3/25
or 28/25
