Fred's frog jumped 7 times as far as al's frog. the two fogs jumped a total of 56
inches. how far did fred's frog jump?

7x+x=56

8x=56

(divide by 8) x=7

So al's frog jumped 7 inches and freds frog jumped 7 times that which is 49 inches, equalling 56 inches altogether:)

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
