A truck can safely carry a one- ton load. It can safely deliver $\frac { 1 } { 5 }$ ton of sand, $\frac { 1 } { 11 }$ ton of gravel , and $\frac { 8 } { 11 }$ ton of cement at one time to a job site.

The total amount of sand, gravel, and cement is $\frac { 1 } { 5 } + \frac { 1 } { 11 } + \frac { 8 } { 11 } = \frac { 35 } { 55 } = \frac { 7 } { 11 } $ ton, which is greater than the one-ton load capacity of the truck. Therefore, it cannot safely deliver all three materials at once.
