Formula for distance between two points:
d = √((x₂-x₁)² + (y₂-y₁)²)
Let point 1 be (-3, 11) and point 2 be (5, 5)
Therefore x₁ = -3, y₁ = 11, x₂ =5, y₂ = 5, and substituting in the formula above.
d = √((x₂-x₁)² + (y₂-y₁)²)
= √((5- -3)² + (5-11)²)
= √((5+3)² + (5-11)²)
= √((8)² + (-6)²) 8² = 8*8 = 64, (-6)² = -6*-6 = 36
= √(64 + 36)
= √(100)
= 10
Distance = 10 units.
The average speed is 4 kilometer per hour
<em><u>Solution:</u></em>
Average Speed is given by formula:
A student walked 1.5 km in 25 minutes and then, realizing he was late, ran the remaining 0.5 km in 5 minutes
Therefore,
Total distance = 1.5 km + 0.5 km = 2 km
Total time taken = 25 minutes + 5 minutes = 30 minutes
Convert 30 minutes to hour
Substituting the values in above formula,
Thus average speed is 4 kilometer per hour
TO CALCULATE APPROXIMATELY THE AMOUNT OR VALUE OF SOMETHING IS CALLED ESTIMATION.
<u>APPROXIMATION AND ESTIMATION ARE SYNONYMS!!!!!! HOPE THIS HELPS!!!!!!!!</u>
