Short answer: 80 * 3.75 = 300. We know that Tim is consistently going at a rate of 80 kilometers per hour. In other words, he would have traveled 80 kilometers in 1 hour, 160 km in 2 hours, and so on. If we want to find a formula for this, we can say that distance = speed * time. In this case, distance = 80 * 3.75, distance = 300.
