Mason:

time = t

V = 6 ft/s

Distance = v * t = 6t

Nora:

time = t - 60 [ I passed 1 minute to seconds]

V = 8 ft/s

Dsitance = v*t = 8 (t - 60)

Both distance are equal

6t = 8 (t-60)

6t = 8t - 480

8t - 6t = 480

2t = 480

t = 480/2

t = 240 s

Mason had been swimming for 240 seconds when both had swan the same distance.
