Answer:
1 kilometer/minute
Step-by-step explanation:
If we want to find the speed, we must divide the distance by the time.
![s= \frac {s}{t}](https://img.qammunity.org/2021/formulas/physics/college/sdno3jlfg55ski3w106my98misek3sc7im.png)
The truck travels a distance of 10 kilometers in 10 minutes.
![d= 10 km\\t=10 min](https://img.qammunity.org/2021/formulas/physics/college/gpdoe0xz7vwl7ygkdahblzgb8a221gpawh.png)
Substitute the values into the formula and divide.
![s=(d)/(t)](https://img.qammunity.org/2021/formulas/physics/college/x4v9v76tg3too281afd5tr59p2m29ftr3b.png)
![s=(10 km)/(10min)](https://img.qammunity.org/2021/formulas/physics/college/mw86ygxr54zemr3f9x0s6emuuq80xkhcan.png)
![s= 1 km/min](https://img.qammunity.org/2021/formulas/physics/college/jwwsjx4kqtm7w003jorxqn77ic9cfgttq3.png)
The speed of the truck is 1 kilometer per minute.
