Answer:
The circles do intersect.
Step-by-step explanation:
A circle is of the form
(x-h)^2+(y-k)^2=r^2
where,
h = Point on x axis of the circle center
k = Point on y axis of the circle center
So, the center of the circle is at (0,0) and radius is 2 units
The circle center is at the point (2,2) and radius is 2 units.
Hence, the circles do intersect.
Answer:
They will meet at 6 p.m.
Step-by-step explanation:
Let after h hours after the truck left the station the car and the truck meet with each other.
So, the distance traveled by truck in h hours = distance traveled by car in (h - 2) hours.
If the speed of the truck is 45 km/h and the speed of the car is 54 km/h,
Then, 45h = 54(h - 2)
⇒ 9h = 54 × 2
⇒ h = 12 hours.
Therefore, they will meet at 6 p.m. (Answer)
