The 90km/h bus runs between the two stations in 2 hours and 20 minutes.

AnnZ [28]

Answer:

1. distance is 210km

2. distance is 163•3km

Step-by-step explanation:

SPEED=DISTANCE÷TIME

90km/h= X ÷ 2 hrs and 20mins

CHANGE 20 MINS INTO HRS

1 hr = 60mins

? = 20mins

20mins * 1hr= 1/3hr

60mins

Speed=distance÷time

90km/h= X ÷ 21/3

Distance= speed * time

X = 90km/h * 21/3hrs

distance is 210km

Speed=distance ÷

70km/h= X ÷ 21/3hrs

Distance=speed * time

X = 70km/h * 21/3hrs

Answer:

<h2>Bibi ate 6.3 pounds of food, approximately.</h2><h2>Rexy ate 5.7 pounds of food, approximately.</h2>

Step-by-step explanation:

1. What is this situation about?

The situation described is about the amount of food those dogs eat, and its relation with their weights.

2. What are the quantities in this situation?

The quantities are aboth the weight of each dog, and the number of pounds of dog food.

3. What mathematical questions could we ask?

We could ask the pounds of food each dog eats, in proportion with their weights.

4. Answer the question.

To answer that question, we just need to form a proportion.

$\frac{8}{10.5}=\frac{12-x}{x}$

Where $12-x$ is the total pounts Rexy ate, and $x$ is the total pounts Bibi ate.

$8x=126-10.5x\\8x+10.5x=116\\18.5x=116\\x=\frac{116}{18.5} \approx 6.3$

Therefore, Bibi ate 6.3 pounds of food, approximately.

Then, $12-x = 12-6.3 = 5.7$

Which means, Rexy ate 5.7 pounds of food, approximately.

John is 5ft tall and is standing in the light of a 15ft lamppost. His shadow is 4ft long. He walks 1ft father away from the lamp

Dennis_Churaev [7]

The shadow lengthened by 2.25 ft.

Step-by-step explanation:

Height of the lamppost is not needed here.

We can write the ratio as,

5 /4 = x/5

25 = 4x

x = 25/ 4

Now it is not needed to find the length of the new shadow, and so, we need to find the length of the added shadow.

25 / 4 - 16/ 4 = 25 - 16 / 4 = 9/4 = 2.25 ft

Length of the new shadow is 25/ 4 = 6.25 ft

So length of new shadow - length of old shadow = 6.25 - 4 = 2.25 ft shadow lengthened
