Being 250 meters apart, two puppies started running towards each other at the same time. the first puppy ran 1.5 meter per second, while the second one ran 2.5 meters per second. what was the distance between them in half a minute?

The distance between them in half a minute was 130 m

Step-by-step explanation:

Firstly, we will find distance traveled by first and second puppy and then we can find distance between them

First Puppy:

Speed =1.5 m/sec

time =0.5 min =30 second

we know that

distance = speed*time

Second Puppy:

Speed =2.5 m/sec

time =0.5 min =30 second

we know that

distance = speed*time

now, we can find distance between them

so,

The distance between them is

So,

the distance between them in half a minute was 130 m

answer is 67%

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
