Answer 2

Answer: 25 km/hr

Step-by-step explanation: Speed (1)=30 km/hr

Speed (2)= 20 km /hr

average speed (when two uniform speed is already given )= sum of speed / No of different speeds

Remember -unit should be same both could either be in km/hr , m/s or any other unit

average speed = ( 20 +30 / 2) km/hr
