A jumbo-size 90-ounce drink at a certain gas station has 760-calories. How many calories are there in a 28-ounce drink

Step-by-step explanation:

This is a proportion problem.

760 / 90 = x / 28            Cross multiply

90 * x = 760 * 28            Simplify the right side

90x = 21280                   Divide by 90

x = 21280/90

x = 236.4

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
