Question

A man Rides at 54km/hr . He covers a distance 480 m in:

Answer 1

Answer:

Speed: 54 km/h= 54000 m/h

Speed= Distance/Time

54000=480 m / Time

Time: 112.5 hours

Answer 2

Given,

The speed at which a man rides = 54 Km/hr

To find,

The time taken by the man to cover a distance of 480 m.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

Speed (s) = distance traveled (d)/time of journey(t)

=> time of journey(t) = distance traveled (d)/speed (s)

{Statement-1}

The speed at which a man rides

= 54 Km/hr

= (54 × 1000 m)/(3600 s)

{Since 1 Km = 1000 meters and 1 hour = 3600 seconds}

= 15 m/s

Now, according to the question;

The time taken by the man to cover a distance of 480 m

= distance traveled (d)/speed (s)

{according to statement-1}

= (480 m)/(15 m/s)

= 32 s

Hence, the man takes 32 seconds to ride a distance of 480 m.
