we're going to assume that Zeke is driving the same speed for his entire trip to answer this question. to find out his average speed,, we can simply divide 346 by 8 to see how many miles he will drive in 1 hour
346 ÷ 8 = 43.25 mph
so your correct answer can be kept exactly as 43.25 miles per hour or you can round down to simply 43 mph as his average speed.
let me know if you have any further questions
