Question

Niharika cycles at a speed of 35km/hour and reaches school in 16 minutes. How long will she take if she cycle at 40 km/hour to reach school.

Answer 1

Answer:

The answer to this question is 9 min.

Step-by-step explanation:

According to this question,

Niharika cycles to her school at 35km/hr and reaches in 16 minutes.WE have to find the amount she takes if she cycles to school at 40km/hr.

Before we find the time taken by her, we first have to find the amount of distance travelled by her.

Distance = Speed x Time

Distance = 35 x 16

Distance = 560 km

Now since we have found the distance travelled, we can find the time also.

Time = Distance/Speed

Time = 560km/40

Time = 9 min

So, Niharika takes 9 min to reach her school if she cycles at 40km/hr.

Mark me as the brainiest answer. Thank you.

Answer 2

Answer:
Step-by-step explanation:
Distance= speed*Time
Distance=35kmph* 16 min
Distance=35kmph*16/60hr
Distance=35km*16/60
Distance=560/60km
Distance=28/3km
Therefore,Time taken by her to cover 28/3km at a speed of 40kmph = Distance/speed
=28/3km/40kmph
=28/3*40hr
=7/30hr
Or 7*60/30=14 minutes
