A B
50 mph 60 mph
so let's recall that d = rt, distance = rate * time.
both cars start out at the same time, say "t" hours.
after "t" hours car A has covered say "d" miles, since there's a total of 1320, then car B must surely had covered the slack, or 1320 - d.
For continuous interest,
Future value = Pe^(rt)
P=present value = $500
e=napien constant=2.7182818284
t=time in years = 8 years
r=annual interest = 0.05
Future value
=500(e^(0.05*8))
=500e^0.4
=745.91 (to the nearest cent)
The product of a number is always one. Both numbers cancel each other in the numerator and denominator.
For example: 1/3*3= 1 1/4*4=1
300 minutes 60 times 5 equals 300
