The train from Metropolis A to Metropolis B takes 4 hours and 15 minutes. If the rail distance between Metropolis A and Metropolis B is 250 miles, how fast must the train average? mph

Respuesta :

4 hours and 15 minutes =4+15/60=4.25 hours

the average speed of the train = 250/4.25=58.82mph

Answer:

[tex]58\frac{14}{17}\text{ mph}[/tex]

Step-by-step explanation:

Given, the distance = 250 miles,

The time taken by rail to cover this distance = 4 hours 15 minutes

[tex]=4\frac{15}{60}\text{ hours}[/tex]

[tex]=4\frac{1}{4}\text{ hours}[/tex]

[tex]=\frac{17}{4}\text{ hours}[/tex]

Since,

[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]

Hence, the speed of the train

[tex]=\frac{250}{17/4}[/tex]

[tex]=\frac{1000}{17}=58\frac{14}{17}\text{ mph}[/tex]
