Final answer:
When driving at 60 mph, you would travel 616 feet in 7 seconds.
Step-by-step explanation:
When driving at a constant speed of 60 mph, you can calculate the distance travelled in 7 seconds by using the formula: distance = speed x time.
Converting 60 mph to feet per second, we get 88 feet per second.
Therefore, when driving at 60 mph, you would travel 7 x 88 = 616 feet in 7 seconds.
