Answer:
300 km
Step-by-step explanation:
If he drives for 3 hours at a rate of 80 km per hour, multiply:
[tex]80*3=240[/tex]
Now we need to find how far he goes in 45 minutes. There are 60 minutes in an hour, so write and simplify:
[tex]\frac{45}{60}=\frac{3}{4}[/tex]
45 is three quarters of an hour, so multiply that by 80 km per hour:
[tex]\frac{3}{4}*80\\\\\frac{3*80}{4}\\\\ \frac{240}{4} =60[/tex]
Add the distances together:
[tex]60+240=300[/tex]
At a rate of 80 km per hours, in 3 hours and 45 minutes, Tim drives 300 km.
Finito.
