You must: (a) dim your high beams for oncoming vehicles by the time they are within feet of your vehicle, and (b) dim your high beams when the vehicle you are following is within feet.

500,300

Explanation:

Safety measures on the road can be regarded as activities and precautions that should be taken in order to improve safety on the road which means to reduce risk.

Whenever one is driving with high-beam lights on, one of safety precautions that must taken into consideration is that ;

You must: (a) dim your high beams for oncoming vehicles by the time they are within 500 feet of your vehicle

(b) dim your high beams when the vehicle you are following is within 300 feet.

When you dim the beam, the oncoming vehicle won't be blind, he/she would be able to see clearly. As you are approaching a car with high-beams, look at the right edge of your own lane and use Conner of your eyes to watch the oncoming car to avoid been blind .

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts
