Answer:
a) 168 minutes or 2 hours and 48 minutes
b) He can fit 3 in 42 minutes
Explanation:
so first find how long it takes for one.
56 minutes divided by 4 is 14.
so, it takes 14 minutes for each one.
so, to fit 12 then you will need to multiply 12×14 to get 168.
168 minutes = 2 hours and 48 minutes.
and for the last part on part B, 14×3=42. He can fit 3 in 42 minutes.
Hope this helps some!
Have a great day!
