Jonathon fills 1/5 of a toffee box in 1/30
of a minute. How much time will he take to fill a full box?
Answer provided by our tutors
The average rate of Jonathon is:
V = (1/5)/(1/30) box/min
V = 6 box/min
Let 't' represent the time needed to full out 1 box.
V = 1/t
t = 1/V
t = 1/6 min
t = 60*(1/6) sec
t = 10 sec
Jonathon needs 10 seconds to fill a full box.
