Please help me solve these problem i have no idea how to do this.
720m/d= ____ m/min
1.5gal/min=______ qt/h
32yd/min=_____in./s
0.85km/s=______m/min
80mi/h=_______ft/s
20fl oz/min=_______qt/day
substitute the old units with the new units
I will do the 2nd last
80 mi/h = ?? ft/s
1 mile = 5280 feet
1 hour = 3600 seconds
so 80 mi/h = 80(5280) ft/3600 s
= 422400/3600 ft/s
= 352/3 ft/s or appr. 117.33 ft/s
You can do the others in the same way, all you have to know how many units are in each of the related measurements.
Thank You!!! so much i total get it now, thanks.. ;}
Sure, I can help you solve these problems! Let's go step by step.
1. To convert from meters per day (m/d) to meters per minute (m/min), you need to keep in mind that there are 24 hours in a day and 60 minutes in an hour.
- First, divide 720m by 24 hours to find the meters per hour: 720m ÷ 24h = 30m/h.
- Then, divide 30m by 60 minutes to find the meters per minute: 30m ÷ 60min = 0.5m/min.
So, 720m/d is equal to 0.5m/min.
2. To convert from gallons per minute (gal/min) to quarts per hour (qt/h), you need to remember that there are 4 quarts in a gallon.
- Multiply 1.5gal by 4 quarts/gallon to find the quarts per minute: 1.5gal × 4qt/gal = 6qt/min.
- Then, multiply 6qt by 60 minutes to find the quarts per hour: 6qt × 60min = 360qt/h.
So, 1.5gal/min is equal to 360qt/h.
3. To convert from yards per minute (yd/min) to inches per second (in./s), you need to remember that there are 3 feet in a yard and 12 inches in a foot, and 60 seconds in a minute.
- First, multiply 32yd by 3ft/yd to find the feet per minute: 32yd × 3ft/yd = 96ft/min.
- Then, divide 96ft by 60 minutes to find the feet per second: 96ft ÷ 60min = 1.6ft/s.
- Finally, multiply 1.6ft by 12in/ft to find the inches per second: 1.6ft × 12in/ft = 19.2in/s.
So, 32yd/min is equal to 19.2in./s.
4. To convert from kilometers per second (km/s) to meters per minute (m/min), you need to remember that there are 1000 meters in a kilometer and 60 seconds in a minute.
- First, multiply 0.85km by 1000m/km to find the meters per second: 0.85km × 1000m/km = 850m/s.
- Then, divide 850m by 60 seconds to find the meters per minute: 850m ÷ 60s ≈ 14.17m/min (rounded to two decimal places).
So, 0.85km/s is approximately equal to 14.17m/min.
5. To convert from miles per hour (mi/h) to feet per second (ft/s), you need to remember that there are 5280 feet in a mile and 60 minutes in an hour.
- First, multiply 80mi by 5280ft/mi to find the feet per hour: 80mi × 5280ft/mi = 422,400ft/h.
- Then, divide 422,400ft by 60 minutes to find the feet per minute: 422,400ft ÷ 60min = 7,040ft/min.
- Finally, divide 7,040ft by 60 seconds to find the feet per second: 7,040ft ÷ 60s ≈ 117.33ft/s (rounded to two decimal places).
So, 80mi/h is approximately equal to 117.33ft/s.
6. To convert from fluid ounces per minute (fl oz/min) to quarts per day (qt/day), you need to remember that there are 128 fluid ounces in a gallon and 24 hours in a day.
- First, divide 20fl oz by 128fl oz/gal to find the gallons per minute: 20fl oz ÷ 128fl oz/gal ≈ 0.15625gal/min.
- Then, multiply 0.15625gal by 24 hours to find the gallons per day: 0.15625gal × 24h ≈ 3.75gal/day.
- Finally, multiply 3.75gal by 4 quarts/gallon to find the quarts per day: 3.75gal × 4qt/gal = 15qt/day.
So, 20fl oz/min is approximately equal to 15qt/day.
