d. 75
e. 80

Respuesta :

Answer:

D

Step-by-step explanation:

[tex]\frac{50}{40}[/tex] = [tex]\frac{x}{60}[/tex]  we can simplify 50/40 to 5/4

[tex]\frac{5}{4}[/tex] = [tex]\frac{x}{60}[/tex]

4 x 15 = 60

5 x 15 = 75

Answer:

  • d. 75

-----------------------------

A train travels 50 mi and car travels 40 mi in within same time.

The ratio of distances remains same if we assume they have constant speed.

Let the train travels t mi while the car travels 60 mi, then the ratios are:

  • train / car = 50 / 40 = t / 60
  • t = 50*60/40
  • t = 75

The matching option is d.
