Question

the odometer of a bike reads 1500 km at the start of the trip and 2500 km at the end of the trip. if the bike took 15 hours, calculate the average speed of the bike in k/h and m/s. *​

Answer 1

Answer:

S = 2500-1500= 1000km= 1000×1000m

t= 15×60×60

V=?

s=vt

v=s/t

v=1000×1000/15×60×60

v=1000000/54000

v=18.5m/s

Answer 2

Answer :

• Speed in km/h => 200/3 km/h

• Speed in m/s => 500/27 m/s

Given :

• The odometer of a bike reads 1500 km at the start of the trip and 2500 km at the end of the trip and the bike took 15 hours to complete the journey.

To Find :

• Average speed of the bike in km/h and m/s.

Step By Step Explanation :

Total distance covered will be final reading of odometer - reading of the odometer before the journey.

Total distance = 2500 - 1500 => 1000 km.

Time taken to complete the journey = 15 hours.

As we know ⤵

$\dag\boxed{ \bf{ \pink{Speed = \cfrac{Distance}{Time}}}}$

So let's do it !!

$\bf \: By \: substituting \: the \: values \downarrow$

$:\implies\sf Speed= \cancel\cfrac{1000}{15} \\ \\ :\implies\bf Speed= \cfrac{200}{3} \: Km/h$

Speed in m/s will be ⤵

$:\implies\sf Speed= \cfrac{200}{3} \times \cfrac{5}{18} \\ \\ :\implies\sf Speed= \cancel\cfrac{1000}{54} \\ \\ :\implies\bf Speed= \cfrac{500}{27} \: m/s$

Therefore,

Speed in Km/h => 200/3.

Speed in m/s => 500/27.
