Answer: See explanation
Step-by-step 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
