Answer:
Temperature after 1 minute = 184 ° F
Step-by-step explanation:
starting temperature = 200 °F
rate of decrease = 8% per minute
Temperature lost = 8% of 200 = 8/100 × 200 = 0.08 × 200 = 16 °F
It therefore means that after 1 minute, the cup of coffee loses 16 °F,
∴ Temperature after 1 minute = (starting temperature) - (lost temperature)
= 200 - 16 = 184 °F

Step-by-step explanation:
Answer: it took them 7 hours to travel 49 miles.
Step-by-step explanation:
The exploratory scouts travel 32 miles in eight hours.
Speed = distance/time
It means that the speed at which they travelled 32 miles is
32/8 = 4 miles per hour.
The next day they had traveled 49 miles so they increase the speed by 3 mph. It means that the speed at which they travelled 49 miles is
4 + 3 = 7 mph
Time = distance/speed
Therefore, the time it took them to travel the 49 miles is
49/7 = 7 hours
