Answer:D1 = 7.5×2/60= 0.25km
D2= 7.5×2/60= 0.25km
Total Distance= 0.25+0.25=0.50km
Total time taken = 2+2+56=60min= 1 HR
Average speed =total distance/ total time
Average speed= 0.50/1= 0.50 km/hr

Answer:
S1=v×t1
=7.5×2÷60
=0.25 km
S2=v×t2
=7.5×2÷60
=2.5 km
S=s1+s2
=0.5 km
T=t1+t2+t3
=2+2+56
=60 minute
=1 hr
Avg speed =s/T
=0.5÷1
