Answer:

Question :-

A vulture takes 50 seconds to travel a distance of 1.5 km. What is the speed of the vulture?

Answer :-

Speed of a vulture is 30 m/s.

Explanation :-

Given :-

Distance travelled = 1.5 km

Time taken = 50 seconds

To Find :-

Speed of a vulture?

Solution :-

❏ Converting units of distance into meters :-

We know that,

✪ 1 km = 1000 m ✪

Therefore,

↪ Distance in m = (1.5 × 1000) m

➢ Distance in m = 1500 m

Now, we have distance travelled by vulture as well as time taken by vulture. So, we can easily find speed by using formula of speed.

We know that,

✪ \bf Speed = \dfrac{Distance}{Time}Speed=

Time

Distance

✪

Putting values in formula we get,

⇒ \sf Speed = \dfrac{150\cancel{0}}{5\cancel{0}}Speed=

5

0

150

0

⇒ \sf Speed = {\cancel{\dfrac{150}{5}}}Speed=

5

150

➠ \bf\red{Speed = 30\:m/s}Speed=30m/s

∴ Speed of a vulture is 30 m/s.
