Question

Rubi walks from her house 1 3/4 miles to get her bike. Then she rides 2 1/3 miles to reach her car. Finally she drives the car 3 3/8 miles through the goal to win the triathlon. What is the total distance she travels from the house to the goal?

Answer 1

7.46 miles she has traveled from her house to the goal.

Explanation:

total distance traveled = 1 3/4+ 2 1/3+ 3 3/8 miles

=7/4 + 7/3+ 27/8 ( converting the mixed numbers into improper functions)

= 7(6) +7(8) +27(3)/24 (taking LCM)

=42 +56+ 81/24 (adding)

= 179/24

= 7.46 miles
