You can put this solution on YOUR website! two cars are driving from montgomery, alabama to little rock, arkasas. if the first car leaves san francisco at 6am and travels at 48 miles per hour, and the second car leaves at 8am and travels at 64 miles per hour, how long will it take for second car to catch up to the first?
..
let x= hours first car traveled
x-2=hours second car traveled
distance = speed*travel time (equal for both cars)
48x=64(x-2)
48x=64x-128
16x=128
x=8 hrs
ans:
The second car will catch up with the first car in 8 hrs.
