While shopping after her birthday, Annie bought 2 pairs of jeans and 3 shirts and spent $127.

Her twin sister Hallie bought the same items,

consisting of one pair of jeans and 4 shirts, and

spent $116.

How much does a pair of jeans cost?

How much does a shirt cost?

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
