Answer: J) 2.27 minutes
======================================================
Explanation:
Let's convert from feet to miles. To do this, we divide by 5280 since there are 5280 ft in a mile.
8981 ft = 8981/5280 = 1.70094696969697 approximately
The bridge is roughly 1.7009 miles long.
Traveling at 45 mph would mean that it takes...
time = distance/speed
time = (1.7009 mi)/(45 mph)
time = 0.0378 hours
Multiply this by 60 to convert to minutes
0.0378 hours = 0.0378*60 = 2.268 minutes
This value rounds to 2.27 minutes
This final answer is approximate since nearly every other value mentioned is also approximate.
