The sound of thunder from a bolt of lightning was heard 2.6 seconds after the lightning hit, from 895 meters away. What was the speed of sound to the nearest tenth of a meter per second?

Use speed = distance ÷ time. The sound traveled 895 meters in 2.6 seconds, so its speed was 895 ÷ 2.6 ≈ 344.23 meters per second. Rounded to the nearest tenth, that is 344.2 meters per second, choice D.
