Question

Jada walks at a speed of 3 miles per hour. Elena walks at a speed of 2.8 miles per hour. If they both begin walking along a walking trail at the same time, how much farther will Jada walk after 3 hours?

Answer 1

Answer:

0.6 miles

Step-by-step explanation:

Jada:

3 miles ×3 hours= 9 miles

Elena:

2.8 miles × 3 hours = 8.4 miles

Equation:

9 - 8.4 = 0.6

Answer 2

Step-by-step explanation:

Since this scenario already uses mph (miles per hour), you can know that Jada had walked 3 miles in one hour and Elena had walked 2.8 miles in 1 hour. So, simply multiply both numbers by 3 to get how far they would have traveled in 3 hours.

3 * 3 = 9

2.8 * 3 = 8.4

So, after 3 hours, Jada has walked 9 miles and Elena has walked 8.4 miles. This means that if you subtract Elena's total distance from Jada's total distance, you will find how much farther Jada has walked

9 - 8.4 = 0.6 miles

Answer:

In 3 hours, Jada will have walked 0.6 miles farther than Elena.
