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

The total cost after tax to repair kimbers phone screen is represented by 0.04(30h)+30h,where h represents the number of hours i
yuradex [85]

0.04(30h) is the part of the expression that represents the amount of tax she must pay. This part shows that 0.04 (4%) is the tax rate, 30 is the amount of money needed to pay per hour (h). Taxes are a percentage of the actual price added on to the actual price, so that means that 30h is the actual price, 30 dollars an hour, and 0.04(30h0 are the taxes she has to pay.
