Question

many cycles at 6 kg/he how long will it take to reach her Aunt house which is 12 km away if you cycle at speed of 4 km/hr how long would she take ​

Answer 1

Answer:

3 hours

Step-by-step explanation:

Speed of the cycle = 6 km / hr Distance travelled to reach her Aunt’s house = 12 km ∴ Time requried = (Distance travelled)/Speed = 2 hours Let the time required when the speed of the cycle is 4 k,/hr be x hours. The speed of the cycle and the time required to the travel the same distance are in inverse proportion. ∴ 4 × x = 6 × 2 ∴ x = (6 x 2)/4 = 3 hours ∴ Mary will require 2 hours if she is cycling at 6 km/hr and 3 hours if she is cycling at 4 km/hr to reach her Aunt’s house.Read more on Sarthaks.com - https://www.sarthaks.com/861196/mary-cycles-per-hour-how-long-will-she-take-reach-her-aunts-house-which-away-she-cycles-speed
