Ivan and Adeline are in a classroom with a chalkboard. They are standing on different halves of the board, and on each half, the

solong [7]

Answer:

The number of times Ivan and Adeline have the same number written on the board is 6.

Step-by-step explanation:

Consider the procedure as follows:

On each half of the board, the number 2 is written.
On Ivan's teacher's signal, Ivan multiplies the number on his side of the board by -2 and writes the answer on the board, erasing the number he started with.
Adeline does the same on each signal, except that she multiplies by 2.
The teacher gives 10 signals in total.

Consider the numbers on each half of the board:

Ivan Adeline

2 2

2 × -2 = -4 2 × 2 = 4

-4 × -2 = 8 4 × 2 = 8

8 × -2 = -16 8 × 2 = 16

-16 × -2 = 32 16 × 2 = 32

32 × -2 = -64 32 × 2 = 64

-64 × -2 = 128 64 × 2 = 128

128 × -2 = -256 128 × 2 = 256

-256 × -2 = 512 256 × 2 = 512

512 × -2 = -1024 512 × 2 = 1024

-1024 × -2 = 2048 1024 × 2 = 2048

Thus, the number of times Ivan and Adeline have the same number written on the board is 6.

Jack and jill exercise in a 25.0-m-long swimming pool. jack swims nine lengths of the pool in 2 minutes and 34.5 seconds, while

grin007 [14]

Jack swims a distance of 9*25.0m=225.0 meters is 2 min and 34.5 seconds.

2 min and 34.5 seconds are 2*60sec +34.5 sec= 154.5 s

Jill covers 10*25.0m = 250 m in 154.5 s.

$\displaystyle{ Average\ Speed= \frac{Distance\ traveled}{Time \ of \ travel}\\\\$

$\displaystyle{ Average \ Velocity = \frac{Displacement}{time}$

thus,

the speed of Jack is : 225.0 meters /154.5 s =(225/154.5) m/s = 1.46 m/s

the speed of Jill is : 250.0 meters /154.5 s =(250/154.5) m/s = 1.62 m/s

Assuming Jack and Jill depart from point 0 towards the positive direction,

each even number of lengths, means Displacement = 0, and each odd number of lengths means Displacement = 25 m

So, average Velocity of Jill is 0,

average velocity of Jack is 25/ 154.5 = 0.16 m/s

Answer:

Average Speed of Jack : 1.46 m/s

Average Speed of Jill : 1.62 m/s

Average Velocity of Jack : 0

Average Velocity of Jill : 0.16 m/s
