This is a proportion problem so you set up related units to convert them:

[tex] \frac{11.9ft}{3 days}}[/tex] × [tex]\frac{1 day}{24 hr}}[/tex] × [tex]\frac{12in}{1ft}}[/tex] = [tex]\frac{42.8in}{72hr}[/tex]

Since it is over 72hr, divide 42.8in by 72hr = 1.98333333...

So the plant grows about 2 in per hour

Answer:

1.98 inches /hr                                                    

Step-by-step explanation:

Growth of tropical giant bamboo in 3 days = 11.9 feet

Growth of tropical giant bamboo in 1 day  =[tex]\frac{11.9}{3}[/tex]

                                                                     =[tex]3.96[/tex]

So, The rate of the growth is 3.96 feet/day

Now we are supposed to convert the rate into inches /hour

1 inch = 12 inches

1 day = 24 hours

So, Rate of the growth in inches per hour =  [tex]3.96 \times \frac{12}{24}[/tex]

Rate of the growth in inches per hour =  [tex]1.98[/tex]

Hence  the rate of the growth in inches per hour is 1.98 inches /hr
