The person whose go-kart travels faster is:
Barry
Alan's go-kart travels 1750 feet per minute.
Barry's go-kart travels 21 miles per hour.
1 mile = 5280 feet

1 mile per hour= 5280/60 feet per minutes
i.e.
1 mile per hour = 88 feet per minutes.
21 miles per hour = 21×88 feet per minute.
21 miles per hour = 1848 feet per minute.
Since,
1848 feet per minutes is greater than 1750 feet per minutes.
Hence, Barry's go-kart is faster than Alan's go-kart.
5x-10= 3x+10
5x-3x= 10+10
2x÷2= 20÷2
x= 10
