Q. Xóchitl, who has already warmed up, immediately starts to pedal at a rate of 18hkm on a stationary bike.She sees that her friend Cowessess has already pedaled 12 minutes at an average rate of 10hkm.Assuming Cowessess's rate stays the same, how long would Xóchitl have to pedal to catch up to Cowessess's distance?minutes
Calculate Cowessess's Distance: Calculate the distance Cowessess has already covered.Cowessess's rate = 10km/hCowessess's time = 12 minutes = 6012 hours (since there are 60 minutes in an hour)Distance = Rate × TimeDistance Cowessess has covered = 10km/h×(6012)hDistance Cowessess has covered = 10km/h×0.2hDistance Cowessess has covered = 2km
Calculate Xóchitl's Time in Minutes: Determine how long it will take Xóchitl to cover the same distance.Xóchitl's rate = 18km/hDistance Xóchitl needs to cover = Distance Cowessess has covered = 2kmTime=RateDistanceTime Xóchitl needs = 18km/h2kmTime Xóchitl needs = 91 hours
Calculate Time in Minutes: Convert Xóchitl's time from hours to minutes.Time in minutes = Time in hours ×60 minutes/hourTime Xóchitl needs in minutes = 91h×60 minutes/hourTime Xóchitl needs in minutes = 960 minutesTime Xóchitl needs in minutes = 6.666… minutes
Round Time to Nearest Minute: Round the time to a value that makes sense in the context of the problem.Since we cannot have a fraction of a minute in this context, we can round the time to the nearest whole minute.Time Xóchitl needs in minutes = 7 minutes (rounded up from 6.666... minutes)
