### Instruction:
John uses 5 liters of fuel per km to travel. How many liters of fuel should John plan to use if he plans to travel on two trips of 30 km and 20 km?

### Response:
 Umbali jumla kwa safari mbili ni kilomita 30 + kilomita 20 = <<30+20=50>>50 kilomita.
John anapaswa kupanga kutumia lita 5 za mafuta kwa kilomita * 50 kilomita = <<5*50=250>>250 lita kwa safari mbili.
