Answer:
60miles
Step-by-step explanation:
if they drove x miles in the city and y miles on the highway then you know that
x + y = 280
x/12 + y/20 = 16
x + 12y/20 = 16*12 = 192
8y/20 = 88
y = 220
x = 280-y = 280-220 = 60
Answer:
18 km/hr
Step-by-step explanation:
To find the unit rate, we must find the rate in kilometers per hour.
Let’s divide the total kilometers by the total number of hours.
unit rate = kilometers/hours
Juan rode 72 kilometers in 4 hours.
unit rate = 72 kilometers/ 4 hours
unit rate = 72 km/4 hrs
unit rate = 18 km / hr
The unit rate is 18 kilometers per hour.
The growth of the bacteria is expressed as:
<span>B(t) = 4 e^0.8t
</span>
where t is the time in units of hours. If the bacteria is allowed to grow for 8 hours then the number of bacteria present would be,
<span>B(t) = 4 e^0.8(8)
</span><span>B(t) = 2407</span>
