Answer:

1) 8.073 (multiply 0.621 by 13km)

2)1,320,000,000(5280ft times 250,000)

3)37.850(10,000 divided by 264.2)

4)4hrs

5)157680000

(60 seconds in one minute and 60 min in one hr so 60 times 60 =3600 in one hr. then multiply 3600 by 24 for the entire day which is 86400sec. Then multiply that day by 365 which is 31536000 times 5 years which gets us our total of 157680000 seconds.

6) 758000 L

1 gal = 3.79 L so we have to multiply 3.79 times 200,000 which gets us 758000

2) we need to find how many feet are in a mile. 1 mile= 5,280. so 5280 times 250,000 = 1320000000  

3) 264.2 gal= 1 cubic meter so 10,000/264.2= 37.850

4) 1 hr= 60 min = 4hrs and 58 minutes roughly

5) 60 sec is 1 minute= so 60 times 60(the minutes in
