3)convert the lenght of 56.43 ft to its equivalent measurement in meters.
4)change the speed of 72.4 miles per hour to its equivalent in meter per second?
5)how many grams are in 17 lbs?
6)which is faster 55 mi/h or 40 km/h?
7)which is faster 80 mi/h or 40 m/s?
8)Imagine the water is leaking from a container,at a rate of 1.2 ml/h if this rate dose not change,how many liters of water will be lost in a week?
note:(1mi=1.609km)

cardiovascular diseases (diseases of the heart and blood vessels) are the leading case of death worldwide . to address this problem , biomedical engineers have designed various artificial hearts , and some day surgeons may routinely implant these in patients whose own hearts are failing.before implanting such a device in a patient , asurgeon needs to have an idea of how long it might be expected to work before needing to be replaced . if an artificial heart is capable of pumping at least

liter of blood before failure,how long will it probably last in a patient if their average heart rate is 72 beats per minutes, and average stroke volume
( the amount of blood pumped with each stroke)
?is 70 mi
