Answer the last question fast because tomorrow is my test

Dear student,


amount of water flowing will be the volume of the water in the river which is in the form of a cuboid for 1 minute.
V = L*B*H
B = 60 m
H = 3 m

we need to find L which will be the length of the river (imagine a river equal to that length) from the rate given
in 1 hour, distance = 2.4km = 2400 m
in 1 minute, distance = 2400/60 = 40 m

so, V = 40 * 60 * 3 = 7200 m³ 

Therefore  water flowing per minute into the sea is 7200 m³
