Question

a cyclist covers 950 m in 5 minutes. Find his speed in km/hour.​

Answer 1

Step-by-step explanation:

Assuming uniform speed, 950 m is covered in 5 minutes.

Thus the speed is 950 m / 5 min = 190 m/ min.

You asked for speed in km / hr .

1 km = 1000 m and 1 hr = 60 min.

Let us go one step at one time.

So if the cyclist covers 190 m / min, then in 60 minutes he will travel 190*60 = 11,400 m per 60 minutes.

11,400 m/60 minutes = 11,400 m/ hr because 11,400 m = 11.400 km.

Thus, speed in km/ hr = 11.400 km/ hr.
