Question

The following table shows the distance travelled by 3 birds and time taken to travel.

Bird	Meters travelled	Seconds
Sparrow	8	2
Woodpecker	10	5
Bluebird	12	4

Choose the correct option(s).

• A. Woodpecker is slowest
• B. Sparrow is fastest
• C. Bluebird is fastest
• D. Sparrow is slowest

Answer 1

Answer: (A), (B)

Sparrow is fastest

To find out the fastest and slowest bird, we have to find out speed of each of the bird.

Sparrow travelled 8 meters in 2 seconds.
Speed of Sparrow $=8÷2=4$ meters per second

Woodpecker travelled 10 meters in 5 seconds.
Speed of Woodpecker $=10÷5=2$ meters per second

Bluebird travelled 12 meters in 4 seconds.
Speed of Bluebird $=12÷4=3$ meters per second

Let's compare the speeds of 3 birds.
$\because 4>3>2$

Hence, Sparrow is fastest and Woodpecker is slowest.
