Please make sure to show all work. When you compose your assignment, make sure to re-type the

problem questions before starting your calculations. Work can be submitted as a

Microsoft Word or PDF document (as long as appropriate work is included). Feel free to scan your work

prior to sending in the assignment.

1. If the temperature outside is 10° F, calculate this temperature in degrees Celsius (° C). Please

express your answer to one decimal place accuracy.

1𝐹 = −17.2222°𝐶

𝑇ℎ𝑒𝑟𝑒𝑓𝑜𝑟𝑒;

10𝐹 = (10 ∗ −17.2222)

= −172.2°𝐶

2. A meteorologist reports that a thunderstorm is producing heavy rain at the rate of 6 centimeters

per hour. Calculate this rate in inches per hour. Please express your answer to one decimal

place accuracy.

1𝑐𝑚 = 0.393701𝑖𝑛𝑐ℎ𝑒𝑠

9𝑐𝑚 = (9 ∗ 0.393701) 𝑖𝑛𝑐ℎ𝑒𝑠

= 3.5 𝑖𝑛𝑐ℎ𝑒𝑠.

𝑇ℎ𝑒𝑟𝑒𝑓𝑜𝑟𝑒, 6 𝑐𝑒𝑛𝑡𝑖𝑚𝑒𝑡𝑟𝑒𝑠 𝑝𝑒𝑟 ℎ𝑜𝑢𝑟 = 3.5 𝑖𝑛𝑐ℎ𝑒𝑠 𝑝𝑒𝑟 ℎ𝑜𝑢𝑟

3. If a river is discharging at 9,000 cubic feet per second at its delta, calculate the river’s velocity if

the width is 40 meters and the depth is 3.5 meters. Please express your answer using English

units and to one decimal place accuracy.

𝑅𝑖𝑣𝑒𝑟 𝐷𝑖𝑠𝑐ℎ𝑎𝑟𝑔𝑒 = 9000𝑐𝑢𝑏𝑖𝑐 𝑓𝑜𝑜𝑡 𝑝𝑒𝑟 𝑠𝑒𝑐𝑜𝑛𝑑

1 𝑐𝑢𝑏𝑖𝑐 𝑓𝑜𝑜𝑡 = 0.0283168 𝑐𝑢𝑏𝑖𝑐 𝑚𝑒𝑡𝑟𝑒

𝑇ℎ𝑒𝑟𝑒𝑓𝑜𝑟𝑒, 9000 𝑐𝑢𝑏𝑖𝑐 𝑓𝑒𝑒𝑡 = (9000 ∗ 0.0283168) = 254.8512 𝑐𝑢𝑏𝑖𝑐 𝑚𝑒𝑡𝑟𝑒

𝐴𝑟𝑒𝑎 = 40𝑚 ∗ 3.5𝑚 = 140 𝑠𝑞𝑢𝑎𝑟𝑒 𝑚𝑒𝑡𝑟𝑒

𝑅𝑖𝑣𝑒𝑟 𝑣𝑒...
