Answer:
220 yd / min
Step-by-step explanation:
miles /hr x hr / min x yd / mile = yd / min
( see how things 'cancel out ' and you are left with yds per minute?)
Substitute in the values :
15 / 2 x 1 / 60 x 1760 = 220 yd/min
220 yards
she travels 15 miles in 2 hours , that is
15 × 1760 = 26,400 yards in 120 minutes
distance travelled in 1 minute = 26,400 ÷ 120 = 220 yards
