Anita and Brad are each riding on the same path. Anita began riding at start of the path and is riding at rate of 18 mile per ho
ser-zykov [4K]

Answer:

They will be at the same position after 2 hours.

Step-by-step explanation:

Here, it should be asked the time it will take for Anita to catch Brad.

Anita began riding at start of the path and is riding at rate of 18 mile per hour.

This means that, after t hours, her position will be given by:

A(t) = 18t

Brad begin from a sport 10 mile ahead of her and I riding at rate of 13 mile per hour

This means that, after t hours, his position will be given by:

B(t) = 10 + 13t

After how much time will they be at the same position?

This is t for which:

A(t) = B(t)

So

18t = 10 + 13t

5t = 10

t = \frac{10}{5}

t = 2

They will be at the same position after 2 hours.

An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled usin
ioda
The height at time t is
h(t) = 144 - 16t²

When t = 0, then h = 144.
Therefore the height from the ground is 144 when the object is dropped.

When the object reaches the ground, h = 0.
Therefore
144 - 16t² = 0
t² = 144/16 = 9
t = 3 s

Answer:
The object reaches the ground in 3 seconds.
