Question

how much time will be taken by a cyclist to cover 54 km if he is moving with the speed of 18 km per hour​

Answer 1

Answer:

Here we have given distance =54km

Speed of the cycle is 18km/hr

We have to find time required to complete the distance

Step-by-step explanation:

We know that

Time = Distance /speed

Time = 54/18= 3 hour

Thus time required is 3 hour.

Answer 2

1000 m is 1 km and 3600 sec is 1 hr

1000 m/3600 sec = 1 km/ hr

=> 1 km/hr = 1000/3600=10/36=5/18 m/sec

so as per your question 25 m/sec= 25*18/5=90 kmph. Ans
