Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
Tony goes on 5 rollercoasters while he is at the park. The first went 50 miles per hour. The second went 62 miles per hour. The third when 73 miles per hour. The fourth when 70 miles per hour. His average speed during the day was 59 miles per hour. How fast was the fifth coaster?

### Response:
 ความเร็วรวมของรถไฟเหาะทั้งห้าคันคือ 295 เพราะ 59 x 5 = <<59*5=295>>295
รถไฟเหาะคันสุดท้ายไปด้วยความเร็ว 40 ไมล์ต่อชั่วโมง เพราะ 295 - 50 - 62 - 73 - 70 = <<295-50-62-73-70=40>>40
