You can put this solution on YOUR website! Two hikers walking in opposite directions start from camp at the same time. The average rate of the westbound hiker is 2 km/hr more than the rate of the eastbound hiker. If they are 15 km apart after 1,5 hr, what is the rate of each hiker
..
let x=rate of eastbound hiker
x+2=rate of westbound hiker
distance=rate*travel time
1.5x+1.5(x+2)=15
1.5x+1.5x+3=15
3x=12
x=4
ans:
rate of eastbound hiker=4 km/hr
rate of westbound hiker=6 km/hr
