A barrel floats down a river past two flags that are 100 meters apart. The time it took for the barrel to pass each flag is shown. What is the speed of the river’s current?

I don't see the actual times — could you tell me the two times (or upload the picture)?
Method: if the barrel passes the first flag at time t1 and the second at t2 (in seconds), the current speed v = distance / time = 100 m / (t2 − t1). Convert units if you like (m/s to km/h: multiply by 3.6).
Example: if the times differ by 40 s, v = 100/40 = 2.5 m/s = 9.0 km/h. Provide the two times and I’ll compute the exact speed.
