James drives 30 mph for half an hour and then twice as long for twice the speed.  How far did he drive in total?
His first drive was 30*.5=<<30*.5=15>>15 miles
The next leg was .5*2=<<.5*2=1>>1 hour
The speed of the trip was 30*2=<<30*2=60>>60 mph
So he drove 60*1=<<60=60>>60 miles
So in total he drove 60+15=<<60+15=75>>75 miles
#### 75
