In this question, we're trying to find how many miles a car travels in 15 minutes.
We know that the car travels at 85 mph.
However, we need to know how many miles it travels per minute.
To find this, we would divide 85 by 60.
85 ÷ 60 = 1.4166
The car drives at a speed of about 1.42 per minute.
We need to know how far it goes in 15 minutes, so multiply 1.42 by 15.
1.42 · 15 = 21.3
The car travels at a approximately 21.3 miles in 15 minutes.

Answer:
0.2
Step-by-step explanation:
Change the divisor 0.16 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
3.22 ÷ 16 = 0.20125
and therefore:
.03220 ÷ .16 = 0.20125
Both calculated to 5 decimal places.
