If 30 students each carry 1.5 liters of clean water daily for 7 days, how many liters of clean water are carried in total?

Step-by-step solution

1. Compute water carried by one student: $1.5\text{ L}\times 7=10.5\text{ L}$ per student.
2. Multiply by 30 students: $10.5\text{ L}\times 30=315\text{ L}$.
