An ostrich can run 25 miles in 40 minutes. How many minutes will it take the ostrich to run 40 miles if it runs at the same spee
fenix001 [56]

The Ostrich will take 64 minutes to cover 40 miles.

Data;

  • rate = 25 miles in 40 minute

<h3>Rate</h3>

To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).

25mi = 40 min\\40 mi = x min

Cross multiply both sides

x * 25 =40 * 40

simplify the value

x*25=40*40\\25x = 1600\\

divide both sides by the coefficient of x

25x = 1600\\25x/25 = 1600/25\\x = 64

From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.

Some friends plotted the locations of their house on a map. brianna's house is at (1,6), Jordan's house is at (5,3). What is one
Rufina [12.5K]
Let
A (1,6)------> location <span>brianna's house on a map
B </span>(5,3)------> location Jordan's house on a map

we know that
One possible path from brianna's house to jordan's house it's a straight line  ( <span>the shortest distance)</span>

using a graph tool
see the attached figure

find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]
d=√25----> d=25 units

the distance from brianna's house to jordan's house is 25 units

The astronomical unit (AU) is the mean distance from the sun to the earth.
Mrac [35]
By definition, we have to
 1 AU = 1.5 * 10 ^ 8Km
 a comet is 2.3 AU from the earth, which means that we must transform this unit to kilometers.
 2.3 AU = (2.3) * (1.5 * 10 ^ 8) = 3.45 * 10 ^ 8km
 answer
<span> 3.45 × 10,superscript,8,baseline, km
