Xóchitl needs to pedal for approximately 6.67 minutes at a rate of 18 km/h to catch up to Cowessess, who has already covered 2 km in 12 minutes at a rate of 10 km/h.
To calculate how long Xóchitl would have to pedal to catch up to Cowessess's distance, we need to use the formula for distance: distance = speed × time.
Since Cowessess has already pedaled for 12 minutes at an average rate of 10 km/h, we can calculate the distance Cowessess has covered as follows:
- Convert minutes to hours: 12 minutes = 12/60 hours = 0.2 hours.
- Cowessess's distance = 10 km/h × 0.2 h = 2 km.
Now we need to find out how long it will take Xóchitl, who pedals at 18 km/h, to cover the same distance.
Xóchitl's time = distance / speed
Xóchitl's time to cover 2 km = 2 km / 18 km/h = 1/9 hours
Convert hours to minutes: 1/9 hours × 60 minutes/hour = 6.67 minutes
Therefore, Xóchitl must pedal for approximately 6.67 minutes to catch up to Cowessess.
