The car traveled for 1/2 hour at 49 mph, so it must have gone $\"49%2F2=24.5\"$ 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). $\"24.5%2F3.5+=+7\"$ mph.\r
