In March Ms. Turner drove 90 miles. If she drove 3 times as many miles in March as she did in January, then all we need to do at this point is multiply 3 to 90.
90 × 3 = 270
So Ms. Turner drove 270 miles in January.
Ms. Turner then drove 4 times as many miles in February as she did in January, so we will do the same here.
270 × 4 = 1080
Therefore, Ms. Turner drove 1,080 miles in February.
