The Attempt at a Solution
a. no idea
b. m/s^2 / m/s = m(s)/m(s^2) = 1/s ... said seconds but apparently incorrect
c. 1400000000=3600 bills/hour(time) - 10 hrs/day ... t=388889 hours + 10 hrs/day = 16204 days + 10 hrs/day ; 10 hrs/day x 1 day/24 hours =.417 days; 16204 (.417)= 6757 days; 16024 days + 6757 days = 22961 days x 1 yr/365 days = 63 years (wrong as well)
d. 1 m= 100 cm ; 8m (100 cm/m) = 800 cm ; 800 cm (.001 kg/cm)=.8 kg (wrong)
help is greatly appreciated thanks!
