Question 121581This question is from textbook algebra and trigonometry with analiytic geometry
: At 5 A.M. a snowplow, traveling at a constant speed, begins to clear a highway leading out of town. At 8 A.M. an automobile begins traveling the highway at a speed of 49 mi/hr and reaches the plow 30 minutes later. Find the speed of the snowplow.
You can put this solution on YOUR website! The car traveled for 1/2 hour at 49 mph, so it must have gone miles. Since the car left at 8AM, and reached the snowplow 30 minutes later, it must have arrived at the snowplow at 8:30AM. The snowplow covered the same distance, 24.5 miles, but started at 5AM. In other words, the snowplow travelled 24.5 miles in 3.5 hours (8:30 - 5). mph.
