Question 141(i)
The diagram shows the wingspans of different species of birds. Use the diagram to answer the question given below.
How much longer is the wingspan of an Albatross than the wingspan of a Sea gull?

Answer 1

We have, length of the wingspan of Albatross $=3\frac{3}{5}m$
and length of the wingspan of a Sea gull $=1\frac{7}{10}m$
$\therefore$ Difference
$=3\frac{3}{5}-1\frac{7}{10}$

$=\frac{18}{5}-\frac{17}{10}$

$=\frac{36-17}{10}=\frac{19}{10}m$

Hence, the wingspan of an Albatross is $=1\frac{19}{10}m$ longer than the wingspan of a Sea gull.
