Answer 2

As per data given in the question,

We have to determine the speed in Km/Hour if Rajesh covered a distance of 3.5 km in 30 minutes.

As we know that,

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

As here, distance is given in Kilo meter while the time span is given in minutes, so we will convert the minutes into Hours first.

So, converting 30 min. into hour.

As we know that,

1 Hr. = 60 min.

=> 30 min. = 0.5 Hr.

So, now calculating the speed,

We will get it as,

$Speed =\frac{3.5}{0.5} = 7\:Km/Hr.$

Hence, the speed in Km/Hour if Rajesh covered a distance of 3.5 km in 30 minutes will be 7 Kmph.
