lets call time for storm 1 and storm 2 t%5B1%5Dand t%5B2%5D respectively
:
t%5B1%5D%2Bt%5B2%5D=50.....eq 1
15t%5B1%5D%2B35t%5B2%5D=1450..eq 2
:
take eq 1 and re write to t%5B1%5D=50-t%5B2%5D
:
15%2850-t%5B2%5D%29%2B35t%5B2%5D=1450
:
750-15t%5B2%5D%2B35t%5B2%5D=1450
:
20t%5B2%5D=700
:
highlight%28t%5B2%5D=35%29hours
:
t%5B1%5D=50-t%5B2%5D=50-35=highlight%2815%29hours
