Mr.Joseph drives car from A to B at a constant speed. If the speed of the car is increased by 20%, it takes him one hour less than the usual time. If he drives at the constant speed for the first 100km before increasing the speed by 30%, it also takes him one hour less than the usual. The distance of AB is ..........km.
Gọi S là quãng đường
v là vận tốc
t là thời gian Mr.J đi thường ngày
=>\(\dfrac{S}{120\%v}=t-1\)
\(\dfrac{100}{v}+\dfrac{S-100}{130\%v}=t-1\)
=>\(\dfrac{S}{120\%v}=\dfrac{100}{v}+\dfrac{S-100}{130\%v}\)
<=>\(\dfrac{130S}{156v}=\dfrac{15600+120S-12000}{156v}\)
<=>\(10S=3600\)
<=>\(S=360\)
