Question

What is the volume in mL of 1.00 pint of heavy cream. 1.9 The speed limit on many Australian highways is 100 km hr . Convert this to mi hr(round to the nearest whole number) 1.10 What is the volume in mL of 1.00 pt of heavy cream? 1.11 The average density of whole milk is 1,034 g cm . What is its density 1.12 It is 2374 mi between Phoenix, Arizona, and Philadelphia, Pennsylvania. 1.13 The legendary racehorse Secretariat won the 1973 Kentucky Derby in lb gal-? What is this distance in km? with a time of 1 min, 59.4 s. The course is 1.25 mi long. Calculate the horse's average speed in mi hr . 35

Explanation / Answer

1. speed limit is =100 km/hr

since 1.61 km= 1miles

100 km= 100*1/1.61 miles =62.1 miles

hence 100 km/hr= 62.1 miles/hr

2. 1 pt= 473.2 ml

3. milk density = 1.04 g/cm3

1000 gm = 1kg and 1lb =0.4535 kg and 1000cc= 1L and 3.76 L= 1gallon

hence density = 1.04*10-3 kg/10-3 L =1.04 Kg/L =1.04/0.4535 lb/1/3.76 gallon = 8.62 lb/gallon

4. 1 mil =1.61 km and 2374 mi= 2374*1.61 km =3822.14 km

5. 1hr= 60min and 1min= 60 sec

hence 1 hr= 60*60 =3600 sec

1 min 59 sec= 60+59= 119 sec= 119/3600 hr =0.033056hr

hence 1.25ml is covered in 0.033056 hr

hence speed = 1.25/0.033056 mi/hr=37.81 mi/hr
