40x = 60x -210
-20x = -210
x = 10.5 hrs
x-3.5 = 7 hrs (Mr. Reed's time)

Answer:
90 seconds
Step-by-step explanation:
If James eats 32 hotdogs in 60 seconds, we want to find how long it would take James to eat 48 hotdogs.
We can use proportion to solve this problem.
If 32:60, then 48:x.
Since it will required more seconds to eat 48 hotdogs, 32 will divide.
If more, less divides.
Therefore


Therefore it will take James 90 seconds if he eats at the same rate
