Question

richard walks every day at a rate of 1 kilometer every 20 minutes at this rate how far can richard walk in 1 hour/

Answer 1

Answer:

Step-by-step explanation:

Richard's speed: Distance / Time

                             Distance =  1 km

                              Time = 20 mins; convert minutes into hours

                              20 mins = __hours?

                               20/60 hours

                            1 km / (20/60)hour = 3 km/hr

Suppose Richard walk in 1  hour, so the distance he walked is :

Time * Speed = Distance = 1 hour * 3km /hr = 3 km

So Richard walked total 3 kilometres in 1 hour.
