A highway patrol plane flies 1 mile above a flat, straight road at a steady ground speed of 120 miles per hour. The pilot sees an oncoming car and, with radar, determines that the line-of-sight distance from the plane to the car is 1.5 miles, decreasing at the rate of 136 miles per hour. Find the car’s speed along the highway.

62 mph

Step-by-step explanation:

Given that patrol plane is 1 mile above a flat, straight road 

Let h = 1 mile

The horizontal distance x will be achieved by using pythagorean theorem

1.5^2 = h^2 + x^2

x^2 = 2.25 - 1

x = 1.12 miles

Since it is decreasing at the rate of 136 miles per hour, the car will be moving close at

1.12 × speed = 1.5 × 136

Speed = 204/1.12 = 182 mph

Since the plane moves at 120 mph

The the car’s speed along the highway will be

Speed = 120 - 182 = 62 mph

what level of math? also i don't need to be paid if i can you.

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
