A person is travelling at 60mph at a 45mph speed limit road. The person sees a reduced speedlimit sign (35mph) from 30ft away and starts reducing the speed. The reduced speed limit zonestarts after 40ft of the reduced speed limit sign.a. What would be the deacceleration rate for the driver to successfully reduce his/her speedbefore entering the recued speed area. The driver is going in a downhill grade of 5% andthe reaction time is 2.5 sec.b. Do you think it's a good design? State your reason.

We know that 1 mile = 5280 ft; 1 hour = 3600 seconds.Thus,now, the driver was at a speed of 60 mph.…
