Answer:
He drove 30 miles in February.
Step-by-step explanation:
First, let's begin with the number we know - in March, Mr. Flowers drove 100 miles.
In March he drove 10 times as he did in January, which means we can divide 100 by 10 to find out how much he drove in January:
100/10 = 10
In February, he drove three times as he did in January. So we must multiply 10 by 3:
10.3 = 30
Therefore, Mr. Flowers drove 30 miles in February.
