Question

Abena travelled 40% of the distance of her trip alone, went another 35 miles with Saralyn,

and then finished the last half of the journey alone. How many miles long was the journey?

Answer 1

It is known that Abena travelled 40 % of the distance of her trip alone, then 35 miles with Saralyn, and then the last half (50%) alone.

So, she travelled 40%+50%=90% of distance alone and 100%-90%=10% with Saralyn.

10% is 35 miles, therefore, the journey (100%) was $35\times 10=350$ miles long.

Answer: 350 miles.
