Bob makes 10 cents ever 5 seconds. How much an hour does he make

$72.00 per hour

or

7200 cents per hour

Step-by-step explanation:

10 cents every 5 seconds

There are 60 seconds in 1 minute, 60 min in 1 hour, so 3600 seconds in 1 hour.

5x=3600

x=720

10(720):5(720)

7200:3600

He makes 7200 cents every hour

Divide that by 100; he makes $72.00 per hour.

7200 cents or $72

Step-by-step explanation:

he makes 10 cents every 5 seconds

in one hour there are 60 minutes

and there are 60 seconds in a minute

so,

in one minute he makes:

60 / 5 = 12

10cents x 12 = 120 cents per minute

and in one hour he makes

120cents x 60 = 7200 cents

= 7200 cents in one hour

= $72 in one hour

hope this helps :)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
