Answer:
1.49 hrs or 1 hr and 30 minutes approximately
Step-by-step explanation:
if fran go 2.8m up then the river flow at a rate of 0.8m; the since we are taking the speed of fran and river to be constant. the ratio between their speed will always remain constant. that is if 0.8/2.8 = 0.286≈ this will be always constant.
so if he go up 4m then the horizontal length has to be 1.143 because 1.143/4 = 0.286.
now we find the distance between frans initial positon and final position. to find it we use pythagoras theorem.
to find the time divide distance traveled by speed;
4.160/2.8 = 1.49 hrs
The number of boxes fitted in the larger container is found out by the volume of both boxes.
The number of boxes fitted into the larger container is 480.
<h3>What is the volume?</h3>
The volume can be defined as the space occupied by an object in three dimensions.
Given that the edge of the cube box is 1/4 ft. The dimensions of the larger box are 3 ft long, 1 1/4 ft wide, and 2 ft.
The volume of the cube box is calculated as given below.
Where Vs is the volume of the cube box and s is the edge of the cube box.
The volume of the larger box is calculated as given below.
<em />
Where V is the volume, l is length, w is width and h is the height of the larger box.
The number of cube boxes fitted into the larger box is calculated as given below.
Hence we can conclude the number of boxes fitted into the larger container is 480.
