Quãng đường John lái xe được trong 3.5 giờ đầu là 64 x 3.5 = 224 (km)
Quãng đường John lái xe được trong 1.5 giờ cuối là 60 x 1.5 = 90 (km)
Tổng quãng đường John lái xe được trong suốt chuyến đi là 224 + 90 = 314 (km)
The route AB is 60km long. At 7 am, one motorbike travels from A to B with a constant speed. When this motorbike reaches B, it returns to A immediately with the speed increase by 10km/h and reaches A at 10.30 am at the same day. What is the original speed of this motorbike?

Exchange 2h30' = 2.5h
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
Two points A and B are on the same side of line d. The distance from A to d is 10cm, the distance from B to d is 16cm. Calculate the distance from the midpoint C of AB to d.
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.....
