I think it's 10 meters per second.
24 bottles in total.....6 orange and 4 apple
probability of first picking an orange is 6/24 reduces to 1/4
probability of second picking an apple is 4/23
probability of both is 1/4 * 4/23 = 1/23
Isolate the x. Root both sides
√x²< √81
x < 9 is your answer
hope this helps
Katework+jeanwork=6
work alone
Katework=-5+Jeanwork
ad 5 to both sides
Katework+5=jeanwork
subsitute 5+katework for jeanwork
5+katework+kateworkwork=6
subtract 5 from both sides
2katework=1
divide both sides by 2
katework=0.5days
equation would be
jeanwork+katework=6 and
katework=jeanwork-5 are the equations
In order to write 25 letters in 4 days you would need to write 6.25 a day
