Answer:
Speed = 0.0003miles/hr
Step-by-step explanation:
Speed of object = 1 mile/hour
For every meter it travels, its acceleration increases by 1 mile/hour
∆Distance = increase in distance
∆speed = 1 meter
The speed and the distance are constant
Speed = distance/time
Time = distance/speed = 1meter/(1 miles/hr)
Convert meter to miles
1609.34 meters = 1mile
1meter = (1meter × 1mile)/(1609.34 meters)
1 meter = (1/1609.34)miles
Time = distance/speed = (1/1609.34)miles/(1 miles/hr)
Time = (1/1609.34)hr
We are to determine the speed the object would be travelling in half of an hour?
In 1hr, it travels (1/1609.34)miles
In ½hr, it travels = (1/1609.34)(½)hr
Speed = 0.0003miles/hr
It will be travelling 0.0003miles/hr in half of an hour

Let's take length of HK = n
By using trigonometry,
Hence, value of HK = 44 cm
X+5 ≤ -17
Or if it’s y instead of x put that.
