Answer:

a’s average speed is 60km/h

Step-by-step explanation:

x = a’s average speed

60/40 = 90/x

Cross multiplication:

60x = 40x90

60x=3600

Divide both sides  by 60

x= 60

valina [46]
The first thing we must do for this case is find the amount of minutes we have then:
 "45 minutes each day, 5 days each week, for 12 weeks":
 (45) * (5) * (12) = 2700 minutes.
 We consider the following conversion:
 1 hour = 60 minutes.
 Therefore the number of hours is:
 (2700) * (1/60) = 45 hours
 Finally the average rate in laps per hour is:
 Average = (1800) / (45)
 Average = 40 laps / hour
 Answer:
 
his average rate in laps per hour is:
 
40 laps / hour

2x+y=6<br> y=6-2x<br><br> Substitution method
Arisa [49]
We can put in 6 - 2x for y:

2x + y = 6
2x +(6 - 2x) = 6
2x + 6 - 2x = 6
6 = 6

Since this statement is true:
x and y are all real numbers.

Hope this helps!

Nooooow this is the story all about how my life got flipped turned upsidedown and id like to take a minute so sit right there and ill tell you how i became the prince of a town called Bel Air.

In west Philadelphia born and raised on the playground is where i spent most of my days. chillin out maxin relaxin all cool and all shootin some b-ball outside of the school

when a couple of guys, they were up to no good, started making trouble in my neighborhood. i got in one little fight and my mom got scared she said "youre moving with your auntie and uncle in bel air"

i begged and pleaded with her day after day, but she packed my suit case and sent me on my way. she gave me a kiss and then gave me my ticket i put my walkman on and said "i might as well kick it."

first class yo, this is bad drinkin orange juice outta champagne glass is this what the people of bel air be livin like? hmmm this might be alright. but wait i hear theyre prissy, bourgeois, all that. is this the type of that they just send this cool cat?

i dont think so, ill see when im there. i hope theyre prepared for the prince of bel air. well the plane landed and when i came out there was a dude who looked like a cop standing there with my name. i aint trying to get arrested yet i just got here i sprang with the quickness like lightning, disappeared.

i whistled for a cab and when it came near the license plate said fresh and it had dice in the mirror. if anything i could say that this cab was rare. but i thought "nah forget it- yo homes to bel air!"

i pulled up to a house about 7 or 8 and i yelled to the cabbie "yo homes smell ya later!" i looked up at my kingdom, i was finally there. to sit on my throne as the prince of bel air.
