Question

A large dump truck can move 1,170 tons/h of gravel from one point to another on a work site. What is this rate in lb/s

Answer 1

The rate of the dump truck is 650
`(lb)/(s)`

Step-by-step explanation:

A large dump truck can move 1,170 tons/h of gravel from one point to another on a work site.

To convert the units from tons/h to lb/s, you should know that:

• 1 ton= 2000 lb
• 1 h= 3600 s (1 h= 60 minutes and 1 minute= 60 seconds)

To carry out the unit conversion you must perform the following steps:

`1170 (ton)/(h)*(2000 lb)/(1 ton) *(1 h)/(3600 s)`

Solving:

`1170 (ton)/(h)*=650 (lb)/(s)`

So, the rate of the dump truck is 650
`(lb)/(s)`
