Gọi S là quãng đường
v là vận tốc

t là thời gian Mr.J đi thường ngày

=>\(\dfrac{S}{120\%v}=t-1\)

\(\dfrac{100}{v}+\dfrac{S-100}{130\%v}=t-1\)

=>\(\dfrac{S}{120\%v}=\dfrac{100}{v}+\dfrac{S-100}{130\%v}\)

<=>\(\dfrac{130S}{156v}=\dfrac{15600+120S-12000}{156v}\)

<=>\(10S=3600\)

<=>\(S=360\)

Xong rầu đó khỏi cảm ơn leuleu
