Let us consider body will start oscillation from point C ,b/w C and D.
First calculate time b/w C and D
V=120cm/sec displacement= 60cm
Therefore time(CD)=60/120=1/2
Same as above time (DC)=1/2
Now
Total Time Period
T=T/2+t(CD)+T/2+t(DC)
T=2π√m/k1/2 . +1/2 . +2π√m/k2/2 +1/2
T=2π(√m/k1+√m/k2)/2+1/2+1/2
T=π{√m/k1+√m/k2}+1
T=3.14(√0.2/1.8+√0.2/3.2)+1
T=3.14(√1/9+√1/16)+1
T=3.14(1/3+1/4)+1
T=3.14×7/12+1
T=1.83+1
T=2.83
