Miranda likes to ride the train, because it always travels at the same comfortable speed. last month, miranda rode the train 90 miles. so far this month, she has ridden 60 miles. last month, she spent one more hour traveling than she has this month? how many hours has miranda spent on the train this month?

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

answer: the correct answer is -32
