A whale swims 200 mi in 5 days which equation can be used to find how many miles is twins in 16 days y = 200 * 16 y = 200 over 16 200 = 16 it's what equals 200 / 5 * 16

The correct equation to find how many miles the whale swims in 16 days would be:

y = (200/5) * 16

This equation takes into account that the whale swims 200 miles in 5 days and calculates how many miles it would swim in 16 days. So, first we divide 200 by 5 to find out how many miles it swims per day (40 miles), then we multiply that by 16 to get the total distance in 16 days.
