To find the time taken in travel, divide an object's distance by its speed. In this instance, 340 / 70 = 4.857142 recurring (that is, 4.857142857142... or 4 and six sevenths) hours. The formula D=rt, where D is distance, r is rate (speed), and t is time, is quite useful later in life, so you should remember it.

340 miles/70 miles per hour = 340 miles/1.167 miles per minute = 291 minutes = 4 hours 51 minutes.
