Question 1203893
<br>
The distance from A to B is 1.6km; and P is 3 times as far from B as from A.  That makes P 0.4km from A and 1.2km from B.<br>
The top of B is 1.3km from P, so we have a right triangle with hypotenuse 1.3km, one leg 1.2km, and the height of B for the other leg.  That makes the height of B 0.5km.<br>
ANSWERS:
P is 0.4km from A
The height of A and B is 0.5km<br>
