To guarantee at least 2 black socks, consider the worst-case scenario where he draws all non-black socks first.

Total non-black socks = 42 (blue) + 15 (red) = 57

To guarantee 2 black socks, he needs to draw enough socks so that even if the first 57 are non-black, the next draws will include at least 2 black socks.

So, he draws 57 (non-black) + 2 (black) = 59 socks.

To find the speed, we use the formula:

Speed = Distance / Time

Given:

Distance = 15 km

Time = 15 minutes = 15/60 = 0.25 hours

Speed = 15 km / 0.25 hours

= 60 km/h

Explanation

Let's analyze the given codes:

Given:

EAT = 5120

BEAT = 25120

Find: TREAT = ?

Step 1: Assign values to each letter based on pattern.

Look at:

EAT = 5120

BEAT = 25120

Let’s break it down:

EAT → 5120

Letters: E, A, T

Now try mapping:

E → 5

A → 1

T → 20

→ So EAT = 5 1 20 → 5120

BEAT → 25120

Letters: B, E, A, T

Using the same pattern:

B → 2

E → 5

A → 1

T → 20

→ BEAT = 2 5 1 20 → 25120

Step 2: Apply same pattern to TREAT

Letters: T, R, E, A, T

Using same letter values:

T = 20

R = ? (Check alphabet position: R = 18)

E = 5

A = 1

T = 20

Now write the number sequence:

T R E A T → 20 18 5 1 20

Join them:

TREAT = 20185120
