Tourists on a kayak at a speed of km / h and a fisherman on a rubber boat at a speed

Tourists on a kayak at a speed of km / h and a fisherman on a rubber boat at a speed of m / s uniformly swim across a lake with a width of m. What value in the condition of the problem is insignificant? Why?

It depends on what question is in the problem. If you need to find the time for which the kayak swims across the lake, the boat speed is not taken into account. If you need to find the time of the boat, the speed of the kayak is irrelevant. If you need to find the ratio of boat and kayak speeds, then the width of the lake is not taken into account.
