Maths question?

3 answers

Sam and Jake live 8 km from each other. Sam skateboards 10 km in the same time as Jake rides his bike 15 km. If they both leave home at the same time and travel towards each other, how far from JAKE'S home will they meet? With working pls :)

total distance covered in 1 hr =10+15= 25 km actual distance to be covered = 8 km jake covers (15/25)*8=4.8 sam covers (10/25)*8=3.2

Let x be the distance from Jake's home. This makes the distance from Sam's home 10x/15 = 2x/3. x + 2x/3 = 8 3x + 2x = 24 5x = 24 x = 24/5 = 4 4/5 km

8-x = x/1.5 x = 4.8 km
