I need answer very urgently.

Solve fast please don't use AI .

Elephant and Giraffe are riding bikes! These two bicyclists are exactly 91 miles apart, and both are traveling at the exact same speed of 10 miles per hour (mph) riding directly toward each other.

Starting at the from the front wheel of Elephant's bike, their super-fast friend Bee flies directly towards Giraffe at a speed of 42 mph. As soon as Bee gets to Giraffe's front wheel, she turns around (instantaneously) and flies towards Elephant. When Bee gets to Elephant, she turns around and heads back to Giraffe, and so forth, flying back-and-forth until the two bicyclists meet.

How many miles will Bee have traveled by the time Elephant and Giraffe meet? (Round to the nearest hundredth of a mile)

(Hint: This problem can be solved easily if broken into parts. Solve for the easiest part first and go from there. What's the easiest part? That's up to you to figure out!)
