2. A bakery truck is 20 mph faster than the speed of the children chasing it. The bakery truck travels 250 miles in the same time it takes the kids to travel 150 miles. Find the speed of the bakery truck and the kids.
**
let x=speed of the kids
x+20=speed of the truck
travel time =distance/speed
..
250/(x+20)=150/x
250x=150x+3000
100x=3000
x=30
x+20=50
ans:
speed of the kids=30 mph
speed of the truck=50 mph
