To find s2, we can use the formula:

s = v * t

Since v1 = v2, we can rewrite the formula as:

s1 = v1 t1
s2 = v2 t2

Given that s1 = 40000 km and t1 = 1200 seconds, we can calculate v1 as:

v1 = s1 / t1
v1 = 40000 km / 1200 sec
v1 = 33.33 km/s

Since v1 = v2, we have:

v2 = 33.33 km/s

Now, we can calculate s2 using v2 and t2:

s2 = v2 t2
s2 = 33.33 km/s 10800 sec
s2 = 359964 km

Therefore, s2 is approximately 359964 km.
