Answer:
The length of KH is 6 units and OH is 6.3 units.
Step-by-step explanation:
Given the figure with lengths LO=5 and OK=4. we have to find the length of OH and KH.
In ΔLOH
By Pythagoras theorem
→ (1)
In ΔKOH,
→ (2)
In ΔKHL,
Using eq (1) and (2), we get
⇒
⇒
Put the above value in eq 2, we get
⇒ KH=6 units.
Answer:
<em>v = 3.75 mph</em>
Step-by-step explanation:
<u>Constant speed motion </u>
An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.
t=12/60 = 0.2 hours. Now compute the speed:
v = 3.75 mph
