Q. Haruka hiked several kilometers in the morning. She hiked only 6 kilometers in the afternoon, which was 25% less than she had hiked in the morning.How many kilometers did Haruka hike in all?kilometers
Identify Morning Hike Expression: Let x be the number of kilometers Haruka hiked in the morning.Identify the expression for 25% less than the distance she hiked in the morning.Expression for afternoon hike: x−25%(x)= x−0.25x
Set Up Equation for Afternoon Hike: We found: Expression for afternoon hike is x−0.25xWe know: Value for afternoon hike is 6 kilometersSet up an equation to find x, the distance hiked in the morning.Equation for afternoon hike is 6=x−0.25x.
Solve for Morning Hike Distance: We found: 6=x−0.25x Solve for x. x−0.25x=6x(1−0.25)=60.75x=6x=6/0.75x=8 Haruka hiked 8 kilometers in the morning.
Calculate Total Distance Hiked: Calculate the total distance hiked by Haruka.Total distance hiked = Distance hiked in the morning + Distance hiked in the afternoonTotal distance hiked = 8 kilometers (morning) + 6 kilometers (afternoon)Total distance hiked = 14 kilometers
