Question

1. 870 feet in 15 minutes
2. 3096 meters in 72 seconds

find how far the object travels in the given amount of time.

1. 18 hours

moves 2 meters every 3 hours.

1. 24 seconds

rises 5 stories every 6 seconds.

Explanation:

Question 11:

Step1: Find the rate per hour

The object moves 2 meters every 3 hours, so the rate per hour is $\frac{2}{3}$ meters per hour.

Step2: Calculate distance in 18 hours

Multiply the rate per hour by 18 hours: $\frac{2}{3} \times 18 = 12$ meters.

Step1: Find the rate per second

The elevator rises 5 stories every 6 seconds, so the rate per second is $\frac{5}{6}$ stories per second.

Step2: Calculate stories in 24 seconds

Multiply the rate per second by 24 seconds: $\frac{5}{6} \times 24 = 20$ stories.

Answer:

12 meters
