Eugene wants to ride his bike at least 40 miles today. The first hour was mostly downhill and he rode 13 miles. Write and solve an inequality to find how many miles per hour Eugene needs to ride to meet his goal.

Rate ≥ 9 miles per hour

Step-by-step explanation:

Eugene wants to ride his bike at least 40 miles today, this means that distance ≥ 40 miles. The first hour was mostly downhill, and he rode 13 miles. He has 3 more hours to ride. Write and solve an inequality to find how many miles per hour Eugene

needs to ride to meet his goal.

Solution:

Eugene needs to ride at least 40 miles today. During the first hour he rode 13 miles. The remaining distance is:

Remaining distance ≥ 40 - 13

Remaining distance ≥ 27 miles

Since he has 3 more hours to ride; to meet his goal, the rate he needs to ride is:

Rate ≥ 27 miles / 3 hours

Rate ≥ 9 miles per hour
