Answer:

see below

Step by Step

<em>Parallel lines have the same slope.</em>

<em>Perpendicular lines have opposite reciprocal slopes (flip and change sign)</em>

line m- neither (5/2 is the reciprocal of 2/5 but not the opposite reciprocal)

line n- perpendicular (-5/2 is the opposite reciprocal of 2/5 so it is perpendicular)

line p- parallel (same slope)

line q- neither

A plane flies over city A and reaches city B, 115 miles away, in 15 minutes. Find the speed of the plane in miles per hour assum

Vera_Pavlovna [14]

So you want to find how many miles are being flown in one hour.

There are 60 minutes in one hour so you want to find how many times 15 goes into 60 so you can then multiply that by 115.

60 / 15 = 4.

Now multiply 115 by 4,

115 x 4 = 460

Therefore the plane is flying at B. 460 mph.
