Carlos made a scale model of a local bridge. The model spans 6 inches; the actual bridge spans

50 feet

Carlo's scaled bridge model spans 6 inch.

Actual bridge spans  50 feet.

We know that,

1 feet = 12 inches.

i.e  =

actual bridge span = 600 inches.

Scale factor of the model is,

=

That means the scale model is 0.01 time smaller than actual model.

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
