It is estimated that a driver takes, on average, 1.4 seconds from seeing an obstacle to reacting by applying the brake or swerving. How far will a car, traveling at 65 miles per hour, travel (in feet) before the driver reacts to an obstacle. Recall that one mile is 5,280 feet.

Answer:

  about 133.47 feet

Step-by-step explanation:

That distance is ...

  distance = speed × time

  distance = (65 mi/h)(1.4 s)×(1 h)/(3600 s)×(5280 ft)/(1 mi)

  = (65×1.4×5280)/(3600) = 2002/15 ft = 133 7/15 ft ≈ 133.47 ft

The car will travel about 133 feet before the driver reacts.
