The Jacksons and the Simpsons were competing in the final leg of the Amazing Race, which was 240 kilometers long. In their race to the finish, the Jacksons immediately took off traveling at an average speed of v kilometers per hour. The Simpsons' start was delayed by an hour. When they eventually took off, they traveled at an average speed that was 40 kilometers per hour faster than the Jacksons' speed. Sadly for them, that didn't help, and the Jacksons won. Write an inequality in terms of v that models the situation.
