See my previous answer to this same question. the vertical angles have to be right angles
(2*40%+x*10<span>0%)/(2+x) = 70%; calculate x !</span>
Nancy's rate=27 mph
Greg's rate=45 mph
t=Greg's time
t+2=Nancy's time
Since they both traveled same distance then:
27(t+2)=45t
27t+54=45t
18t=54
t=3 hours
Greg will pass Nancy after 3 hours
The answer to what is 1,000 to the power of 4 is 1,000,000
