Question

The water under a draw bridge was 15 feet deep at midnight. As the tide went out, the

water depth decreased at a rate of 0.025 feet per minute. Write an equation that can be
solved to find t, the time in minutes it took the water depth to reach 13 feet. How many
minutes does it take to reach that 13 foot depth?
