A puppy and a kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 m/sec, while the kitten can run at a speed of 20 m/sec. How soon will they meet if they simultaneously start running towards each other?

It will take 4 seconds.

Step-by-step explanation:

It takes the puppy 25 seconds and the cat 20 seconds.

20+25=45

180 divided by 45 = 4

= 4 seconds.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

can you rephrase the question ? it is unclear : -)
