You need to use the equation Distance (miles)=Rate (miles/hour) x Time (hours)

Brandi: 2.5 miles=rate (1/2 hour) r=5 miles per hour

Sharna=3.5 miles= rate (3/4 hour) r = 7 miles per hour.

Therefore brandi jogged at a slower rate.

Sharna jogged at a slower rate because she took approximately 1 minute more per mile than Brandi did.
