Answer:
Average Speed is 65 km/hr
Step-by-step explanation:
To get the average speed, first we have to calculate the time spent in the round trip .
Speed= Distance/ time
So, Time= Distance/Speed
Time Outgoing= 300km/ 97km/hr
Time Outgoing=3.0927 hr
Time lunch break =1 hr
Time return= 300km/ 58km/hr
Time Outgoing=5.1724 hr
Total= 3.0927 hr+1 hr+5.1724 hr=9.2651
To get average speed, we have to divide all the distance by the time it took al the trip.
Average Speed= Distance/ time
Average Speed= 600km/9.2651 hr= 64,76 km/hr
Average Speed=64,76 km/hr ≅ 65km/hr
