A train travels 98 kilometers in 4 hours, and then 61 kilometers in 3 hours. What is its average speed?
1 answer:
Speed (velocity)=distance/time
V1=98km/4hr=24.5km/hr
V2=61km/3hr=20.3km/hr
Average speed (velocity)=total velocity/ number
Average speed (velocity)=44.8km/hr/2=22.4
So the average speed is 22.4km/hr
