Answer 1

Answer: See explanation

Explanation:

Average speed = 14.73 miles per hour

Cross-Country Skiing = 0.75

Distance traveled = 14.73 × 0.75 = 11.0475

Rounding off 11.0475 to the nearest whole number will be: = 11

Therefore, Brian's product was reasonable.

Also, rounding off the activity time to the nearest whole number will be:

= 3 + 1.45 + 1.2 + 0.75

= 6.4

= 6 hours
