1.10. An automobile equipped with a thermometer is heading southward at 100 km h, bound for a location 300 km away. During transit, the temperature drops to -5°C at the origin. If the temperature at departure was measured to be 0°C and the tempera- ture tendency measured along the journey is +5°C h-¹, what temperature should the travelers expect at their destination?
