Question

A boat travels 24 km upstream in 6 hrs and 20 km downstream in 4 hrs. The the speed of the boat in still water and water current are resp

Answer 1

distance travelled = 24 + 20
= 44
time taken = 6 + 4
= 10
speed (v) = total distance / total time
= 44/10
= 4.4 m/s

Answer 2

Answer:

✰given:

A boat travels 24 km upstream in 6 hrs and 20 km downstream in 4 hrs

✰to find:

speed of water current=?

✰Solution:

Speed of boat upstream = $\frac{24}{6}$=4 kmph

Speed of boat downstream =$\frac{20}{4}$=5 kmph

Speed in still water = $\frac{4 + 5}{2}$=4.5 kmph

ஃ Speed of the water current = $\frac{5 - 4}{2}$=0.5 kmph
