Answer:
240 minutes (4 hours)
Step-by-step explanation:
the descend 3000 ft every 20 minutes
36000 ÷ 3000 = 12
20*12 = 240 minutes
Answer:
79,200
Step-by-step explanation:
There are 5280 feet in 1 mile, then you just multiply 5280 by the number of miles (15). So 5280 x 15 = 79,200
Writing the equation that governs this situation:
-3C - (2.5C/hr)x = -18C
Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18
Combining like terms: 2.5x = 18-3 = 15
Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.
