Math riddle! !

3 guys walk into a hotel. the hotel charge was $30. each guy payed $10. the owner felt bad bc they were such nice guests. so the owner gave $5 to the bell boy to give to the guys. the bell boy thought for a moment. you can't split $5 w/ 3 guys ( w/ 5 singles quickly ) so he took $2. so he gave the guys the $3. they each get $1 back. so they each paid $9 ( $27 total ) the bell boy took 2 and they paid 27 ( $29 total ) what happened to the other dollar?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

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
