Keri walks her dog every morning. The length of tue walk is 0.55 kilometers on each weekday. One each weekend day, the walk is 1.4 times as long as a walk on a weekday. How many kilometers does keri walk in one week

Answer 1

Kiri walks : 4 km per week

0.5 × 5 + 0.75 × 2 = 2.5 + 1.5 = 4 km per week.

WHY?

Because 0.55 is close to 0.5 and 1.4 is closer to 1.5
