Question

rohan covers a distanceof 10km by running with a uniform speed of 4.5km/h.Sohan runs 1.2km in 15 mins.who runs faster

Answer 1

speed= distance/time
in rohan's case,
4.5=10/time
time=10/4.5
time=2.22hour

in sohan's case,
15min=0.25 hour
time=1.2/0.25
time=4.8 hour

therefore rohan runs faster

Answer 2

Sohan runs faster.

Step-by-step explanation:

It is given that Rohan covers a distanceof 10km by running with a uniform speed of 4.5km/h.

Speed of Rohan  = 4.5 km/h.

Sohan runs 1.2km in 15 mins.

Distance = 1.2 km

Time = 15 mins = 0.25 hours

Formula for speed

$Speed =\dfrac{Distance}{Time}$

Speed of Sohan is

$Speed =\dfrac{1.2}{0.25}$

$Speed =4.8$

Speed of Sohan  = 4.8 km/h.

Since speed of Sohan is greater than the speed of Rohan, therefore Sohan runs faster.
