Question

John can walk 5 2/5 km in one hour. How much distance will he cover in 3 1/4 hours?​

Answer 1

Answer:

17.55 km or 17550m

Step-by-step explanation:

distance john can travel in one hour is 5 2/5 km which means 27/2 km.

distance he can travel in 13/4 hours (3 1/4) is equal to 27/2*13/4 which is equal to 17.55 km or 17550m

Answer 2

$\bf{\underline{\underline \blue{Solution:-}}}$

$\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}$

$\sf {The\: distance\: covered\:by\:John\:in\: 3\dfrac{1}{4} \:hours = 17\dfrac{11}{20} \:Km}$

$\sf\underline{\red{\:\:\: Given:-\:\:\:}}$

• John can walk $\sf{5 \dfrac{2}{5} }$ km in one hour.

$\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}$

$\sf {The\: distance\: covered\:by\:John\:in\: 3\dfrac{1}{4} \:hours = \:?}$

$\bf{\underline{\underline \blue{Explanation:-}}}$

$\dashrightarrow \sf {Distance\: covered\:in\:one\:hour = 5\dfrac{2}{5} \:km}$

$\dashrightarrow \sf {Distance\: covered\:in\:one\:hour = \dfrac{27}{5}\:km}$

$\sf\underline{\green{\:\:\: ThereFore:-\:\:\:}}$

$\dashrightarrow \sf {The\: distance\: covered\:by\:John\:in\: 3\dfrac{1}{4} \:hours = \bigg(\dfrac{27}{5} \times 3\dfrac{1}{4} \:km } \bigg)$

$\dashrightarrow \sf {The\: distance\: covered\:by\:John\:in\: 3\dfrac{1}{4} \:hours = \bigg(\dfrac{27}{5} \times \dfrac{13}{4} \:km } \bigg)$

$\dashrightarrow \sf {The\: distance\: covered\:by\:John\:in\: 3\dfrac{1}{4} \:hours = \dfrac{351}{20} \:Km}$

$\dashrightarrow \sf {The\: distance\: covered\:by\:John\:in\: 3\dfrac{1}{4} \:hours = 17\dfrac{11}{20} \:Km}$

$\sf\underline{\red{\:\:\: Hence:-\:\:\:}}$

$\sf {The\: distance\: covered\:by\:John\:in\: 3\dfrac{1}{4} \:hours = 17\dfrac{11}{20} \:Km}$

$\rule{300}{2}$
