Team tool Bella gathered 15 pounds of wood in 1/3 of an hour.
1/3 of an hour is equal to 1/3 of 60 mins = 1/3 * 60 mins = 20 mins
We have to find their speed in pounds per hour( 60 mins).
Pounds of woods gathered in 1 hour or 60 mins = 15/20*60
= 15 * 3
= 45 pounds
Therefore, their speed in pounds per hour is 45 pounds / hour
Hope this helps ..!!
Thank you :)
