Explanation

To determine significant figures in 10.03:

• All non-zero digits are significant → 1 and 3
• Zeros between non-zero digits are significant → 0 between 1 and 3
• Zeros after a decimal and a non-zero digit are also significant → the 0 after the decimal is significant

So: 1, 0, 0, 3 → 4 significant figures.

Distance from starting point = 3 km.

He goes 5 km North then 5 km South = back to same horizontal line.

So only 3 km East remains.

Explanation

Average speed ≠ average of speeds when distances are equal.  

Use: Average speed = Total distance / Total time

Total distance = 60 + 60 = 120 km

Time for 1st part = 60 km / 60 km/h = 1 hour  

Time for 2nd part = 60 km / 120 km/h = 0.5 hour  

Total time = 1 + 0.5 = 1.5 hours

Average speed = 120 / 1.5 = 80 km/h.

Let's check the pattern for FEDERAL → GFEFSBM

F E D E R A L  

G F E F S B M  

Compare each letter:

F + 1 = G  

E + 1 = F  

D + 1 = E  

E + 1 = F  

R + 1 = S  

A + 1 = B  

L + 1 = M  

Pattern: Each letter is moved 1 step forward in the alphabet

Now apply to AGENCY:  

A + 1 = B  

G + 1 = H  

E + 1 = F  

N + 1 = O  

C + 1 = D  

Y + 1 = Z  

So AGENCY = BHFODZ
