Darean was hiking and descended down a trail from the top of a mountain at a rate of 3 km per hour. what was the total change in location compared to the top of the mountain after 5 hours

The answer is 225 miles per 4.5 hours. hope this ; )

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
