Question

A car is travelling at a speed of 50 km/h. How long will it take to travel a distance of 175 km?

Answer 1

Time is distance / speed = 175/50= 35/10 = 3.5 hours = 3 hours 30 minutes 

Answer 2

Solution :
       velocity = 50km/hr
       Distance = 175 km
 we know that,
         Velocity = distance /time
         time = distance / velocity
                =175 km/ 50 km/hr
                = (175/50)hr
               = 3.5hr
hence Time Taken is 3.5 hours !!
                         or 3.5 *60 minutes
                         = 210minutes
                     or 210 *60 seconds
                       = 12600seconds
Hope this helps You!!!
