Question

25. A tiger runs 25 m in 10
seconds. The speed of tiger is-
(a) 6 Km/h
(b) 7Km/h
(C) 8 Km/h
(d) 9 Km/h​

Answer 1

Answer:

1km = 1000 m

1/1000km = 1m

then, 25m= 25 x 1/1000km

= 1/40km

1hour = 3600 sec

1sec = 1/3600 hrs

10sec= 10 x 1/3600 hrs

= 1/360 hrs

so, we know speed = distance/time

so speed = 1/40km divided by 1/360

which is equal to 9km/hour..

thankyou

Answer 2

The speed of tiger is 9 km/hr.

We know that, $speed = \frac{distance}{speed}$

Given that, distance = 25 m = $\frac{25}{100}$ km

                       time = 10 s = $\frac{10}{3600}$ hr

Thus, $speed = \frac{distance}{speed}$

                    $= \frac{\frac{25}{1000} }{\frac{10}{3600} }$

                    $= \frac{25 * 36}{100}$

                     $= \frac{900}{100}$

                    = 9 km/hr

Thus the speed of the tiger who runs 25 m in 10seconds is 9 km/hr.

• Speed indicates how quickly or slowly an object is moving.
• It gives the amount of time it took to travel a certain distance divided by the distance traveled.
• Speed is inversely correlated with time and directly proportional to distance.
• Knowing the units for distance and time is necessary to calculate the units for speed.
• The units will be in meters per second (m/s) in this example since the distance is measured in meters (m) and the time is measured in seconds (s).
• Different units can be used to indicate speed, distance, and time.
