Question

. A cyclist covers a distance of 50 m in 10 s. Calculate
the speed of the cyclist in (i) m s' (ii) km h!​

Answer 1

Answer: 1.) 5 m./sec. & 2.) 18 km./h.

Explanation: 1.) speed = distance/time = 50/10 = 5 m./sec.

2.) 5m./sec. = 5×18/5 = 18 km./h.

Answer 2

Answer:

5 m/s

18.51 km/hr

Explanation:

Given :

• A distance of 50 metres is covered

• A time of 10 seconds is taken for covering the distance of 50 metres

To find:

• Speed of the cycle in :

• m/s, km/h

Distance = 50 m

Time = 10 seconds

Speed = 50m /10s

Speed = 5 m/s

The speed of the cyclist in m/s is equal to 5

50 m = 0.05 km

Time = 10 seconds = 0.00278 hours

Speed = 0.05/0.0027

Speed = 18.51 km/h

The speed of the cyclist I m/s is 5 m/s and in km/hr is equal to 18.51 km/h
