helpfulness, your churchmates distribute relief goods to different places. Using the church's
vehicle, they travel at a speed of 30 km/hr. How far will your churchmates reach after
25 minutes of travel? Suppose the distance (in km) is represented by x, and the time (in
hours) is represented by y, how far will your churchmates reach if they travel
y+1
hours?
