Question

A migrating bird can travel at a speed of 30 m/s. How far will it travel in 25 minutes at this speed? Give your answer in metres (m), and in kilometres (km).​

Answer 1

$\bold { \red{EXPLAINATION:}}$

GIVEN:

A migrating bird can travel at the speed of 30 m/s

TO FIND:

How far it will travel in 25 minutes at 30 m/s

SOLUTION:

Converting minutes into seconds

$\implies { \mathtt{1 \: minutes =60 sec }}$

$\implies \therefore { \mathtt{25 \: minutes = 25 × 60 sec }}$

$\implies \therefore { \mathtt{25 \: minutes = 1500 \: sec }}$

Distance traveled in 25 minutes,

As we know,

${ \mathtt{speed = \frac{distance}{time}}}$

$\therefore { \mathtt{distance = speed \times time}}$

$\therefore { \mathtt{distance = 30 \times 1500}}$

$\therefore \:{ \mathtt{ distance = 45000 \: m}}$

As 1000 metres = 1 kilometres

$\therefore \: { \mathtt{45000 \:m = 45 \: km}}$

Therefore,

A migrating bird can travel 45000 m or 45 km in 25 minutes
