Answer

We travel 95.33 feet = 95 $\frac{1}{3}$ feet , when we take our eyes off the road for only a second

Work Step by Step

Given: Speed = 65 mi/hr One mile = 5280 feet. Thus 65 miles = 343200 feet. One hour has 60 minutes. One minute has 60 seconds. Thus, One hour has 60 $\times$ 60 seconds = 3600 seconds. Thus according to given speed, In one hour = 3600 seconds, we travel 65 mi = 343200 ft . Thus, in one second we travel $\frac{343200}{3600}$ = 95.33 feet. We travel 95 $\frac{1}{3}$ feet when we look away for only a second.
