james took a 3 - hour bike ride . in the second hour he traveled 6 miles , which was 20 percent farther than he traveled the first hour . if he traveled 25 percent farther in the third hour than he did in the second hour , how many miles did jose travel during the entire ride ?
"let the distance travelled in the first hour be x . thus , 1.2 x = 6 , x = 5 . now , the distance travelled in the 3 rd hour = 6 + 1 / 4 â ˆ — 6 = 7.5 the only option ending with a 0.5 in the decimal place is c . answer : c"
add(add(multiply(divide(subtract(const_100, 20), const_100), 6), 6), multiply(divide(add(const_100, 25), const_100), 6))
