Answer:

8 hours

Step-by-step explanation:

a mam walks 20 km in 5 hours

Answer 2

⇒ Given :-

• A mam walks 20 km in 5 hours.

⇒ To Find :-

• how long would he take in walking 32 km?

⇒ Solution :-

• Distance walked = 20 km

• Time taken = 5 hours

• Speed = Distance ÷ time

                    = 20 ÷ 5

                    = 4 km/hr

• Distance = 32 km

• Speed = 4 km/hr

• ∴ Time taken to travel 32 Km = Distance ÷ time

                                                          = 32 ÷ 4

                                                           = 8 km/hr

Ans. Time taken to travel 32 Km is 8 km/hr
