Answer:
1 hour and 42.85 minutes.
Step-by-step explanation:
It is found from the process of reviewing that experience survey a roadbed in 3 hours.
Hence, in 1 hour the experience survey 
of the roadbed.
Again, it is found that the apprentice survey needs 4 hours to survey the same stretch of road.
So, in 1 hour the apprentice survey does 
of the roadbed survey.
If they work together then in 1 hour, the survey work will be done by (
)= 
parts.
Therefore, the total survey they will complete working together in 
hours i.e. 1 hour and 42.85 minutes. (Answer)

Answer:
Step-by-step explanation:
Divide: 1
3 : 14 = 13 · 4 1 = 1 · 4 3 · 1 = 43
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1
4 is 4 1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - one third divided by one quarter = four thirds.
Area of rectangle=> L•l= 8•5= 40 in²
Area of the triangle=> (b•h)/2= (8•3)/2= 24/2= 12 in²
Area of the shadowed surface is 40-12= 28 in²
