's house and school?
To find the minimum distance between Hemant's house and school, we can draw a diagram:
H -> 3km east -> A -> 2km north -> B -> 1km west -> C -> 2km north -> D -> 1km east -> S
H: Hemant's house
S: Hemant's school
A, B, C, D: intermediate points
Now, to find the minimum distance, we need to find the straight-line distance between H and S. We can use the Pythagorean theorem to do this:
HS^2 = HD^2 + DS^2
where HD is the distance between H and D, and DS is the distance between D and S.
To find HD, we can use the distance formula:
HD = sqrt[(3+1)^2 + (2-2)^2] = sqrt[16] = 4
To find DS, we can use the distance formula again:
DS = sqrt[(1-2)^2 + (2+1)^2] = sqrt[10]
Now, we can substitute these values into the first equation:
HS^2 = 4^2 + 10
HS^2 = 26
HS = sqrt[26]
Therefore, the minimum distance between Hemant's house and school is approximately 5.1 km (rounded to one decimal place).
