Question

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

Answer 1

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

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

Answer 2

Answer:

$58\frac{14}{17}\text{ mph}$

Step-by-step explanation:

Given, the distance = 250 miles,

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

$=4\frac{15}{60}\text{ hours}$

$=4\frac{1}{4}\text{ hours}$

$=\frac{17}{4}\text{ hours}$

Since,

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

Hence, the speed of the train

$=\frac{250}{17/4}$

$=\frac{1000}{17}=58\frac{14}{17}\text{ mph}$
