It was 19 kilometers from the campgrounds to the lake. joel and mario rode their bicycles from the campgrounds to the lake and back again. if the round trip ride took them 2 hours, what was their average speed in kilometers per hour

Joel's and Mario's average speed is 19 kilometers per hour because it took them 1 hour to get from the campgrounds to the lake, which the speed can be found by v=d/t, in which v is velocity, d is distance, and t is for time. And the fact that it took them 2 hours, their speed is constant at the rate of 19 kilometers per hour because a round trip is from the campgrounds to the lake, which is 19 kilometers, and from the lake back to the campgrounds, which is another 19 kilometers.

19 kilometers per hour mark me as brainliest please
