if i walked ¼ km in one hour in how many hours i will move ⅔ km
Answers
EXPLANATION:
In this problem, we are going to use unitary method. In this problem, we will find the time taken in hours for 1 km and then finally find the time taken in hours for 2/3 km by multiplying with that of the time taken for 1 km.
⇒ 1/4 km = 1 hour
⇒ 1 km = (1 ÷ 1/4) hours
[On taking 1/4 as reciprocal, we get 4]
⇒ 1 km = (1 × 4) hours
⇒ 1 km = 4 hours
If you walk for 1 km, it will take 4 hours. Therefore,
⇒ Time taken to walk 2/3 km = Time taken to walk 1 km × 2/3 km
⇒ Time taken to walk 2/3 km = (4 × 2/3) hours
⇒ Time taken to walk 2/3 km = 8/3 hours
Therefore, you have took 8/3 hours to walk 2/3 km distance.
MORE INFORMATION:
⇒ To find single unit, we divide and to find more than single unit, we multiply.
For example, 10 mangoes cost Rs.20. Then, 6 mangoes costs?
⇒ Cost of 10 mangoes = Rs.20
⇒ Cost of 1 mango = Rs. (20 / 10)
⇒ Cost of 1 mango = Rs. 2
⇒ Cost of 6 mangoes = Rs. (2 × 6)
⇒ Cost of 6 mangoes = Rs. 12
