A Jet airplane leaves an airport traveling at a steady rate of 600km/h. another jet leaves the same airport 3/4h later traveling at 800km/h in the same derection. how long will the 2nd jet take to overtake the first?

7/1

you have to make the mixed # to an improper fraction and then when you have to fractions you just multiply across and then simplify

i don't really get what you just said
