Question 1159179: The rate in which a river flows is measured in miles per hour. If a boat travels at a speed of 15 miles per hour down stream and reaches its destination sooner than expected, explain what effect the current had on the rate of the boat.

.

When the boat moves with the current (i.e. downstream), its effective speed (= the speed relative to the banks of the river)

is the sum of the speed of the boat in still water and the speed of the current.


Therefore, traveling with the current takes LESS TIME than in still water.
