A train travels from station A to station B. If the train leaves station A and makes 75 km/hr, it arrives at station B 48 minute
SSSSS [86.1K]

Answer:

  • A) 290 km
  • B) 4 hours
  • C) 72.5 km/h

Step-by-step explanation:

Let distance be d and time t

<u>At 75 km/h speed the distance is</u>

  • d = 75(t - 48 min) = 75(t - 48/60 hours)

<u>At 50 km/h speed the distance</u> is

  • d = 50t + 40

<u>Since the distance is same, we get the equation:</u>

  • 75(t - 48/60) = 50t + 40
  • 75t - 75*4/5 = 50t + 40
  • 75t - 60 = 50t + 40
  • 75t - 50t = 40 + 60
  • 25t = 100
  • t = 4 hours

<u>A) The distance between A and B</u>

  • d = 50*5 + 40 = 290 km

<u>B) Time is </u>

  • 4 hours as found above

<u>C) The speed = d/t</u>

  • Speed = 290/4 = 72.5 km/h

Usimov [2.4K]
Jasmine is reducing the height of the yearbook picture from 5 inches to 2 inches and we are trying to find the percentage of the original height that is the new height.

The original height was 5 inches and the new height is 2 inches.

new/original = 2/5

2÷5 = 0.4

0.4 = 40%

Thus, the new height is 40% of the original height.

Pls help me with this i will give crown
valkas [14]

Answer:

C

Step-by-step explanation:

The easiest way to solve this would be to find the difference between the numbers. We can do -3-(-9) to find the difference of 6. We can then make sure this is true for the rest of the sequence by adding 6 to each number.

-9+6=-3

-3+6=3

3+6=9

9+6=15

Now that we've verified that this is true, we know the answer is C
