Question

1. A football field is about 100 m long.If it takes a person 20 seconds to run its length, how fast were they running?

2. A plane travels 395,000 meters in 9,000 seconds. What was its speed?

Answer 1

The speed of the person running the football field is 5 m/s. The speed of the plane is 43.89 m/s.

Step-by-step explanation:

1. To find the speed of the person running the length of the football field, we divide the distance (100 m) by the time taken (20 s). So, the speed is 100 m / 20 s = 5 m/s.

2. To find the speed of the plane, we divide the distance (395,000 m) by the time taken (9,000 s). So, the speed is 395,000 m / 9,000 s = 43.89 m/s.
