A truck can carry a load of 5000 lb. Assuming that it could be cut to fit, how many feet of steel beam weighing 32.6 lb/ft (poun

yKpoI14uk [10]

For this type of problem,

It is stated that the weight of steel is 32.6 lbs per foot

Meaning, every foot of steel beam weighs 32.6.

So 2 feet of steel beam would weigh 32.6 x 2 = 65.2 lbs

and 3 feet will be 32.6 x 3 = 97.8 lbs

Since we have a limit of 5000 lbs which is the capacity of the truck.

We can have an equation :

$32.6x=5000$

Where x is the number of foot

Solve the value of x by dividing both sides by 32.6 :

$\begin{gathered} \frac{\cancel{32.6}x}{\cancel{32.6}}=\frac{5000}{32.6} \\ x=153.37ft \end{gathered}$

So the answer is 153.37 feet of steel beam

tensa zangetsu [6.8K]

Answer:

18,432 Km/ h

Step-by-step explanation:

Using the conversions

• 1 Km = 1000 m

• 1 hour = 60 × 60 = 3600 seconds

Then

5120 m = $\frac{5120}{1000}$ = 5.12 Km and

5.12 Km × 3600 = 18,432 Km / hour
