Question

Kirino and Ria start a 10 mile race at the same time. If Kirino ran the race at 5 miles per hour and finishes the race 45 minutes after Ria, how fast does Ria run? Answer: ___ miles per hour

SnapAndSolve AI · Accepted Answer

Let Ria's speed be r miles per hour.Time taken by Kirino to finish the race = 10 / 5 = 2 hours.Ria finishes 45 minutes (or 0.75 hours) earlier, so her time = 2 - 0.75 = 1.25 hours.Using the formula distance = speed × time, we have:10 = r × 1.25Solving for r gives:r = 10 / 1.25 = 8 miles per hour.Therefore, Ria runs at 8 miles per hour.
