A man is standing on a building of height 48m. A rope of length 37m connects the top of this building with the top of another building which is taller. The distance between base of the two buildings is 35m. What is the height of the taller building?

45

step-by-step explanation:

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
