Answer: 390 to 600 milliseconds
Explanation: MIT researchers have found an answer in a new study that shows humans need about 390 to 600 milliseconds to detect and react to road hazards, given only a single glance at the road, with younger drivers detecting hazards nearly twice as fast as older drivers.

Explanation:
Kelly drives 448 miles on the highway to visit her cousin. She uses cruise control to drive at a constant speed . Kelly travels 192 miles in the first 3 hours. At that rate, how long will the trip take?
Solution:
Speed is the rate of change of distance with respect to time. The speed of an object tells us how fast the object is. Speed is the ratio of distance travelled to total time take, it is given by the formula:
Speed = distance / time
From the question, Kelly travels 192 miles in the first three hours, hence her speed is:
Speed = distance / time
Speed = 192 miles / 3 hours = 64 miles per hour
At constant speed, the time taken to drive 448 miles is:
Speed = distance / time
64 miles per hour = 448 miles / time
time = 448 miles / 64 miles per hour
time = 7 hours
