**Answer:**

**the expected distance is 4.32 m**

**Explanation:**

given data

half life time = 1.8 × s

speed = 0.8 c = 0.8 × 3 ×

to find out

expected distance over

solution

we know c is speed of light in air is 3 × m/s

we calculate expected distance by given formula that is

expected distance = half life time × speed .........1

put here all these value

expected distance = half life time × speed

expected distance = 1.8 × × 0.8 × 3 ×

expected distance = 4.32

**so the expected distance is 4.32 m**
