Question

Dany is competing in a triathlon comprised of swimming, running, and biking. She starts by swimming $43.5$ miles. Next, she runs $11$ times the distance that she swims. Finally, she bikes $18$ times the distance that she swims. If Dany swims $2.5$ miles, what is the total distance, in miles, Dany travels as she competes?

• A. $75$
• B. $70$
• C. $50$
• D. $65$

Answer 1

The correct option is A $75$

Given that Dany swims $2.5$ miles

And he run $11$ times of distance that swims and $18$ times of distance that swims

Than he run distance $=$ $2.5\times 11=27.5$ miles

And he bikes distance $=$ $2.5\times 18=45$ miles

Then Dany swings running and biking total distance $=2.5+27.5+45=75$ miles
