Answer:
It will take 56 hours to make 8 airplanes
Step-by-step explanation:
Given that,
Carson builds 3 airplanes in 1 3/4 hours i.e. 7/3 hours.
We need to find the time it would take him to make 8 airplanes.
We know that,
3 airplanes = 7/3 hours.
1 airplane = (7/3)×3 hours
= 7 hours
To make 8 airplanes, the required time will be :
T = 8×7
= 56 hours
Hence, it will take 56 hours to make 8 airplanes.
