Efrain and Fernie are on a road trip. Each of them drives at a constant speed. Efrain is a safe driver and travels 45 miles per hour for the entire road trip. Fernie is not such a safe driver. He drives 70 miles per hour throughout the road trip. Fernie and Efrain left from the same location, but Efrain left at 8:00 a. m .,and Fernie left at 11:00 a. m. Assuming they take the same route, write the linear equation that represents Efrain's constant speed. Make sure to include in your equation the extra time that Efrain was able to travel.
