C)18 metres higher
D)89 metres higher

Answer 1

At the end of the week, Brian pole vaulted 0.19 meters higher than at the start of the week, making the correct answer C) 0.19 meters higher.

Step-by-step explanation:

Brian practiced his pole vaulting and achieved different heights during the week. At the start of the week, he vaulted 1.23 meters, and at the end of the week, he vaulted 1.42 meters. To find out how much higher Brian went at the end of the week, we simply subtract the initial height from the final height:

Height at the end of the week - Height at the start of the week = 1.42 meters - 1.23 meters = 0.19 meters.

Therefore, Brian vaulted 0.19 meters higher at the end of the week.
