Question

an auto rickshaw travelled 15 km in 20m fine the speed in km/h and m/s

Answer 1

Answer:

1) 45km/h          2) 12.5 m/s

Step-by-step explanation:

Distance travelled = 15 kilometers

Time taken = 20 minutes

1) km/h

If 15km is travelled in 20mins, to travel in 60mins (1hr), it needs to travel 45km.

So the km/h speed of the auto rickshaw is 45 km/h

2) m/s

20 minutes exactly contains 20 x 60 = 1200 seconds.

So autorickshaw travels 15000 m [15km] in 1200 seconds

So in 1 second, it travels 15000 / 1200 m/s

Which is 150/12

Which is 50/4

Which is 12.5 m/s

Answer 2

Answer:

If the distance traveled by auto in 20 minutes is 15 km, then its speed in km/hr is 45 km/hr and in m/s is 12.5 m/s

Step-by-step explanation:

Given

The distance the auto can travel in 20 minutes = 15km

The distance the auto can travel in 1 minute = 15/20 km

The distance the auto can travel in 60 minutes ( 1 hour) = $\frac{15}{20} *60\\\\= 15*3\\\\= 45 km$

So it can travel 45 km in 1 hour

So the speed in km/hr is 45 km/hr

Speed in m/s = 45 km/hr *5/18

= 2.5 *5

= 12.5 m/s

So speed in m/s is 12.5 m/s
