duyệt đi
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)

Bob drove from City P to City Q. He traveled the first 36km at an average speed of 54km/h. He traveled the remaining 96km at a average speed of 72km/h. Find his average speed for the whole trip.
Thời gian Bob chạy 36km đầu tiên là 36 : 54 = 2/3 h
Thời gian Bob chạy 96km còn lại là 96 : 72 = 4/3 h
Tổng thời gian Bob lái xe từ thành phố P tới thành phố Q là 2/3 + 4/3 = 2 h
Tốc độ trung bình của Bob khi lái xe từ thành phố P tới thành phố Q là (36 + 96) : 2 = 66 km/h

Ai đúng đầu tiên mk tick 3 cái lun
36 km đầu tiên được số km là:
36 x54 =1944 (km)
96 km tiếp theo được số km là:
96 x72=6912 (km)
Tố độ Tb của Bob là:
(6912+1944):(36+96)=667,0909...(km/h)
