Answer:

1. 400km

2. 16 men

3. first boy - 25 × 2 = 50

second boy - 25 × 3 = 75

third boy - 25 × 4 = 100

Step-by-step explanation:

1. 160 ÷ 4 = 40 40 × 10 = 400

2. 4 ÷ 2 = 2 8 × 2 = 16

3. 2 + 3 + 4 = 9 225 ÷ 9 = 25

first boy - 25 × 2 = 50

second boy - 25 × 3 = 75

third boy - 25 × 4 = 100
