Question

Ravi walks at the uniform rate of 5 km/hr.what distance would he cover in 2 hours 24 minutes? ​

Answer 1

Step-by-step explanation:

Ravi walks 5km/hr.

He walks in 1 minute be x.

He walks in 2hours 24 minutes or 144 minutes

= 5/60 = x/144

After doing cross multiplication

= 60 × x = 5 × 144

= 60x = 720

= x = 720/60

= x = 12 km.

Answer 2

Let required distance covered = x km

Speed of man = 5 km/hr

Time   :     Distance         ::      Time                                                                                 :       Distance

1 hour :       5 km             ::     \(2\frac{24}{60} = 2 \frac{2}{5} = \frac{12}{5}hr.\ )              ;           x

                                  (more time, more distance)

x=5×125×1=12

∴ Distance covered = 12 km
