Q. If the depth of a river increases by 2 m and the width remains constant, how does this affect the volume of water if the length of the river is 1000 m? (2019)
A.
2000 m³
B.
1000 m³
C.
4000 m³
D.
3000 m³
Solution
Volume = Length × Width × Depth. If width is constant, Volume increase = 1000 m × Width × 2 m = 2000 m³.
Q. If the depth of a river increases by 2 m and the width remains constant, how does this affect the volume of water in a section of the river that is 100 m long? (2022)
A.
200 m³
B.
100 m³
C.
300 m³
D.
400 m³
Solution
Volume = Width x Depth x Length. Increase in volume = Width x 2 m x 100 m. Assuming width = 1 m, Volume = 1 m x 2 m x 100 m = 200 m³.
Q. If the length of a river is 120 km and it flows at an average speed of 5 km/h, how long will it take for the river to flow from its source to its mouth? (2021)
A.
20 hours
B.
24 hours
C.
30 hours
D.
36 hours
Solution
Time = Distance / Speed = 120 km / 5 km/h = 24 hours.
Q. If the length of a river is 240 km and it flows at an average speed of 4 km/h, how long will it take for the river to flow from its source to the mouth? (2021)
A.
60 hours
B.
70 hours
C.
80 hours
D.
90 hours
Solution
Time = Distance / Speed = 240 km / 4 km/h = 60 hours.
