Question

Fen completed a triathlon race whose total distance is D kilometers. First, she swam a distance of 0.5 kilometer. Then, she rode a bicycle for x hours at an average speed of 20 kilometers per hour. Finally, she ran for 0.5 hour at an average speed of v kilometers per hour.

Answer 1

To find the total distance of the triathlon race, we need to add the distances of each leg. The first leg is 0.5 km, the second leg of cycling is x hours multiplied by 20 km/h, and the third leg of running is 0.5 hours multiplied by v km/h. So the total distance is 0.5 + 20x + 0.5v kilometers.
