Question

Rohan covers a distance of 10 km by running with a uniform speed of 4.5 km/hr. Sohan runs 1.2 km in 15 minutes. Who runs faster?

Answer 1

Step 1, Given data

Distance covered by Rohan = 10 km

Speed of Rohan = 4.5 km/h

Distance covered by Sohan = 1.2 km

Time taken by Sohan = 15 min.

Step 2, Calculations
15 minutes $=\frac{15}{60}hours$ = 0.25 hrs

$Speed=\frac{distance}{time}$

Speed of Sohan $=\frac{1.2}{0.25}$ = 4.8 km/hr

Speed of Rohan = 4.5 km/hr

Hence, Sohan is faster than Rohan.
