Answer:
D
Step-by-step explanation:
To solve this problem, we must first convert the distance
into miles:
distance = 60 ft (1 mile / 5280 ft) + 6 inches (1 foot /
12 inches) (1 mile / 5280 ft)
distance = 0.0114583 mile
To calculate for time:
time = distance / speed
time = 0.0114583 mile / (90 miles / 3600 seconds)
time = 0.458 seconds
<span>time = 0.46 seconds</span>
