Question

Marta walked at 3.3 miles per hour for 0.54 hours. how far did she walk?

Answer 1

This is a proportion, she is walking 3.3 every hour. She walked for 5.4 hours. And we don't know how far she walked so its x/.54. Then you cross multiply which gives you 3.9×.54=x. We multiply those decimals and we get 1.782.
