Noah's drama rehearsal lasted 120 min. It was 18 min longer than Amira's rehearsal. How many minutes were spent on the two rehearsals altogether?
Need a hint?
Find the length of Amira's rehearsal first, then add the two rehearsal times.
Worked answer
- Amira's rehearsal time = 120 - 18 = 102 min.
- Total rehearsal time = 120 + 102 = 222 min.
Answer: 222 min
