A rabbit is 4\,\text{m}4m4, start text, m, end text away from its burrow. Each hop takes it 0.4\,\text{m}0.4m0, point, 4, start text, m, end text farther from the burrow. The following diagram shows that there is a tasty plant that is 6\,\text{m}6m6, start text, m, end text from the burrow. Which equation can we use to determine hhh, the number of hops it takes the rabbit to reach the plant?
