b) 9.

22.5

1. Order the numbers : 5, 12, 15, 22, 23, 24, 25, 25
2. Find the median formula:
[x(n /2) + x (n/2 +1)] / 2
x (n /2) = 22; x(n/2 + 1) = 23
22 + 23 / 2 = 22.5

10

2 * n + 2 = 22 => 2 * n = 20 => n = 10

240m

A train passes the platform in 36 seconds.
The train passes a man in 20 seconds.
The speed of the train is 54km/h.
Speed = Distance/Time
To convert km/h into m/s we multiply by 5/18
Convert speed into m/s
=> 54 x 5/18 = 15 m/s
The length of the train is:
=> 15 × 20 = 300 meter
Distance covered in 36 seconds
=> 36 x 15 = 540 meter
The length of the platform is:
=> 540 - 300 = 240 meter

The length of the platform is 240 meters

The woman works there. She is filling the basket with trash and taking it out to the dumpster.

S (sixteen)

One + One = Two

Wheelbarrow.

To measure half an hour: Light a stick from both sides. It will completely burn off in half an hour.

To measure 45 minutes: Light a stick from both sides and light the other stick from 1 side. After the first stick completely burns that is half an hour later. Light the half burning stick from the other side as well and you get 45 minutes.

Vacuum cleaner.
