Let the real speed of the canoe be x (km/h) (x > 0)
=> Speed downstream: x + 8 (km/h)
Upstream speed: x-8 (km/h)
According to the arle we have (x+8).2 = (x-8).2.5 => 2x+16 = 2.5x - 20 => 0.5x = 36 => x = 72 (km/h)
=> distance from A to B = (72+8).2 = 160km

A person travel from A to B at a constant speed v = 4 km / h. After he travelling \(\frac{2}{3}\) of the distance, he speed up 25% velocities. It takes 28 minutes to go A to B. The length of AB is.....
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
=>\(\dfrac{S}{120\%v}=t-1\)
\(\dfrac{100}{v}+\dfrac{S-100}{130\%v}=t-1\)
=>\(\dfrac{S}{120\%v}=\dfrac{100}{v}+\dfrac{S-100}{130\%v}\)
<=>\(\dfrac{130S}{156v}=\dfrac{15600+120S-12000}{156v}\)
<=>\(10S=3600\)
<=>\(S=360\)

A car left from town A for Town B at 8:30 am and drove at a
constant speed of 80 km per hour. A little later, a truck left from
Town B for Town A at 9:15 am at a constant speed of 100 km per
hour. If they cross each other exactly at mid-way (mid-point) of the
route between town A and B, find the distance (in km) between Town A anhd Town B.

At 7 hours and 30 minutes, an automobile going from A to B, to 11 hours, the cars arrive. The speed of the cars is 60km / h. Calculate the distance AB
Are you sure about ' cars' in the problem. However, I can show you in case the problem can be true.
The car spends 11h-7h30min= 3h30min to go from A to B.
Since the speed of car is 60 km/h.
Applying the operation s=vt, we have
The distance AB=s= 60 × 3h30min= 210km.
