Ajoba and Prav drive to work. Ajoba drives 45 miles in 2.5 hours. Prav drives 74 km in 1 hour 15 minutes. Work out the differenc

amm1812

Answer:

Ajoba: 28.8km/h

Prav: 59.2km/h

The difference in speed is: 59.2-28.8=30.4km/h

Step-by-step explanation:

Ajoba:

d=45mi Convert to km // $45mi(\frac{1.6km}{1mi} )=72km$

t=2.5h

v=? 28.8km/h

Prav:

d=74km

t=1h15m or 1.25h

v=? 59.2km/h

$Formula: d=v*t$

Solve for v;

$v=\frac{d}{t}$

$v=\frac{72km}{2.5h} \\v=28.8km/h$

--------------------------------------------

$v=\frac{d}{t}$

$v=\frac{74km}{1.25h} \\v=59.2km/h$

Make R the subject<br> <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7BP%3D10%28Q-3R%29%7D%7BR%7D" id="TexFormula1" title=" \frac

I must assume that you meant the following:

10(Q-3R)

P = ----------------

Multiplying both sides by R, we get PR = 10R(Q-3R), or PR = 10RQ - 30R^2.

Rearranging these terms so that powers of R are in descending order:

30R^2 - 10RQ + PR = 0

Factoring out R, we get

R(30R - 10Q + P) = 0. This has two solutions:

R = 0, and 10Q - P

30R = 10Q - P, so that R = --------------

ch4aika [34]

Answer:

6 pencils per student

Explanation:

We know that there are 150 pencils and 25 students; therefore to find the number of pencils each student gets, we divide 150 by 25

Hence,

150 pencils / 25 students = 6 pencils / student.
