When driving 60 miles per hour on the highway, looking ahead about 15 seconds from where you are translated to?

At 60 miles per hour, you need to calculate that into minutes or seconds. At 60 miles per hour multiplied by 1 hr/60 minutes gives you 1 mile per minute. This can be translated into 5280 feet per minute since 1 mile is 5280 feet. At 5280 feet per minute, one can multiple that by 1 minute/60 seconds to get 88 feet per second and then multiple that by 15 seconds to give you 1320 feet from the point you started.
