How fast (in miles per hour) did he drive the first 3 hours? "He drove 56mph the first 3 hours." 

Explain how you got your answer. "I got my answer by divding the miles he drove (168) by how many hours it took (3) to get 56." 

If he continues to drive at that rate, how many hours will it take him to go the 280 more miles? "It will take him 5 more hours." 

Explain how you got your answer. "I divided the miles he needs to travel (280) by the mph he would be going (56)."
