The length of time, in hours, it takes a train to travel to city B varies inversely with the train’s speed. The train Carole is traveling on is moving at a speed of 70 miles per hour, and it takes her 4 hours to arrive. If the train Steve is traveling on is moving at a speed of 50 mph, how long will it take him to arrive at City B?

6/42: 3, 6/9 and 8 to 12 are all equivalent because to get from 2 to 6 you multiply by 3, and to get from 3 to 9 you multiply by 3. to get to 8 from 2 you multiply by 4 and to get from 3 to 12 you multiply by 4.  hope this !
