Question

Connie and two of her friends completed a 10 mile bike relay each friend wrote an equal part of the race what distance did each friend ride

Answer 1

If Connie and her two friends are completing the relay, this means that there are three people. 

If they each rode an equal part of the race this means that we must divide the 10 miles (the distance ridden) by 3 (the number of racers).

As a fraction this equals 3 and 1/3 and in a decimal this equals approximately 3.33
