Một người chạy từ tỉnh A đến tỉnh B hết 5 giờ. Trong 2 giờ đầu mỗi giờ ô tô chạy được 46 km, giờ thứ ba ô tô chạy được 52 km, hai giờ sau mỗi ô tô chạy được 43 km. Hỏi:
a) Quãng đường từ tinh A đến tỉnh B dài bao nhiêu km
b) Trung bình mỗi giờ ô tô chạy được bao nhiêu km
\(a,\)( Mình giải từng bước ra nhé ) :
2 giờ đầu đi được số ki-lô-mét là :
46 x 2 = 92 ( km )
Hai giờ sau đi được số ki-lô-mét là :
43 x 2 = 86 ( km )
Quãng đường từ tỉnh A đến tỉnh B dài số ki-lô-mét là :
92 + 52 + 86 = 230 ( km )
\(b,\)Trung bình mỗi giờ ô tô chạy được số ki-lô-mét là :

Một ô tô chạy từ tỉnh A đến tỉnh B mất 5 giờ. Trong 2 giờ đầu, mỗi giờ ô tô chạy được 46 km, giờ thứ 3 ô tô chạy được 52 km, 2 giờ sau mỗi giờ ô tô chạy dược 43 km. Hỏi quãng đường từ tỉnh A đến tỉnh B dài bao nhiêu km và trung bình môic giờ ô tô chạy được bao nhiêu km?
Quãng đường ô tô đi được trong hai giờ đầu là:
\(46\times2=92\left(km\right)\)
Quãng đường ô tô đi được trong hai giờ sau là:
\(43\times2=86\left(km\right)\)
Quãng đường từ tỉnh A đến tỉnh B dài số ki-lô-mét là:
\(92+52+86=230\left(km\right)\)
Trung bình mỗi giờ ô tô chạy được số ki-lô-mét là:
\(230\div5=46\left(km\right)\)
Bn lm đúng rồi nhé
Một ô tô chạy từ tỉnh A đến tỉnh B . Trong hai giờ đầu mỗi giờ ô tô chạy được 46 km , giờ thứ ba ô tô chạy được 52 km , hai giờ sau mỗi giờ ô tô chạy được 43 km thì đến tỉnh B . Hỏi trung bình mỗi giờ ô tô chạy được bao nhiêu km
Trong ba giờ ô tô đi được :
46 + 52 + 43 = 141 ( km )
Trung bình mỗi giờ ô tô đi được :
141 : 3 = 47 ( km )
Đáp số : 47 km

Một ô tô chạy từ tỉnh A đến tỉnh B.Trong 2 giờ đầu,mỗi giờ ô tô chạy được 46 km , giờ thứ 3 ô tô chạy được 52 km,2 giờ sau mỗi giờ chạy được 43 km đến tỉnh B.Hỏi trung bình mỗi giờ ô tô chạy được bao nhiêu ki-lô-mét?
một ô tô chạy từ tỉnh A, nếu chạy mỗi giờ 60 km thì ôtô đến B lúc 15 giờ.nếu chạy mỗi giờ 40 km thì ôtô đến B lúc 17gio. tính quãng đường AB
Tỉ số giữa 2 vận tốc là : 60:40==3/2 Vì khi đi cùng một quãng đường thì vận tốc tỉ lệ nghịchvới thời gian nên : «Nếu thời gian đi quãng đường AB với vân tốc 60km /h là 2 phần thì là 3 phan nhu the»
Mot phan thời gian nhiều hơn ứng với :
17-15=2(gio)
Vậy với vận tốc 60 km /h ô tô đi từ A đến B mất :
2 + 2=4(gio)
Quãng đường AB dài là :
60 4= 240(km)

Một ô tô chạy từ tỉnh A đến tỉnh B trong 5 giờ. Trong 3 giờ đầu, mỗi giờ ô tô đi được 44,4km. Trong hai giờ cuối ô tô đi được 86,8km. Hỏi trung bình mỗi giờ ô tô đó đi được bao nhiêu ki-lô-mét ?
trong 3 giờ đầu cả 2 ô tô đi được là:
44, 4 x 2= 88,8(km)
trung bình mỗi giờ ô tô đi được là:
(88,8+ 86,8) : 5= 35,12(km)
phần nãy mình bị nhầm nhé cái này mới đúng.
