If the speed of a vehicle was reduced from 65 miles per hour to 35 miles per hour, by approximately how many kilometers per hour was the speed reduced? (1 kilometer = 0.62 mile, rounded to the nearest 0.01 mile)

reduced speed comes out to be 48.3 km/hr

Explanation:

intial speed = 65 miles per hour

final speed = 35 miles per hour

reduced speed = initial speed - final speed

                          =  65  - 35

                          =  30 mile/hr

1 km = 0.62 mile

1 miles =  1.61 km/hr

so reduce speed in (km/hr) = 30 ×1.61 km/hr

                                             =  48.3 km/hr

hence the reduced speed comes out to be 48.3 km/hr

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
