Help with math please? Thanks.?

1) You drive from Chicago to St Louis, a distance of 290 miles. Your average speed is 60mph. How many hours does the trip take?



2) The lipleurodon could grow to 25 meters in length. Use the fact that 1in=2.54cm to convert to the length to feet. Round to nearest foot.



3) You mow a lawn for $20 per lawn. You also work at a restaurant for $7.50 per hour. Write an equation for the total amount of money you can earn. Then find three different ways to earn $300 during one week.Help with math please? Thanks.?
1) time=distance /(divided by) speed

time= 290/60

time=4.83 hours



2) 1 meter = 100 centimeters

25*100=2500 centimeters

2500*2.54=6350 inches

6350/12= 529 feet

I think that's right.



3) You could only mow lawns: 300/20= 15 lawns

You could only work your job: 300/7.50=40 hours

Or do a little of both: 300=(20*6) +(7.50*24)
1) 290/60 = 29/6 = 4 hours 50 minutes



2) 25 meters = 2500 cm



2.54 cm = 1 inch

2500cm = 2500/2.54 "



= 2500/ 2.54X12 ' = 2500/30.48= 82.02 ' ANSWER = 82 '



3) No of times you mow a lawn = x

No of hours in restaurant = y



20x + 7.5y = 300



Give different values to either x or y .

e.g.

y = 8 x= 12Help with math please? Thanks.?
1)5hrs, 50mins

2)about10 feet

3)??



3 is unanswerable,



you could technically(but not realistically) mow 60 lawns in one week, or one day for that matter and make $300. you never specified how much time you could spend mowing lawns or how long it would take.
