Answer:
Time=3 hrs 7 mins 30sec / 3.125 hrs
Avg speed=76.8 km/hr
Step-by-step explanation:
speed=distance/time
time=distance/speed
part I
speed1=30km/hr distance1=60km
time1=60/30=2hrs
part II
speed2=160km/hr distance=180km
time2=180/160=3.125hrs (or) 1hr 7 mins 30 sec
total time taken=time1+time2= 2+1.125=3.125hrs
Average speed=total distance covered/total time taken
=(60km+180km)/3.125hrs
=240/3.125= 76.8km/hr
