Find the distance between A(1, -1) and B(4, 3).
Greeley [361]

Answer:

<h2>The answer is 5 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(1, -1) and B(4, 3)

The distance between them is

|AB|  =   \sqrt{ ({1 - 4})^{2} +  ({ - 1 - 3})^{2}  }  \\  =  \sqrt{( { - 3})^{2} +  ({ - 4})^{2}  }  \\  =  \sqrt{9 + 16}  \\  =  \sqrt{25}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 5 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\

We have the final answer as

<h3>5 units</h3>

Ilya [14]

Answer:

Bob drove from home to work at 75 mph. After work the traffic was heavier, and he drove home at 40 mph. His driving time to and from work was 1 hour and 9 minutes. How far does he live from his job?

=================

Avg speed for the round trip = 2*75*40/(75+40) = 6000/115 = 1200/23 mi/hr

RT distance = 1200/23 * 69 minutes * 1 hr/60 mins =

= 60 miles

30 miles each way
