Question
A jogger runs 5.0 km in 33 min. What is the speed ofthe jogger? (1.2) T/I(a) 0.15 m/s(b) 2.5 m/s(c) 0.25 m/s(d) 2.8 m/s
Solution
First, we need to convert the distance from kilometers to meters and the time from minutes to seconds because the speed is asked in meters per second.
1 km = 1000 m, so 5.0 km = 5.0 * 1000 = 5000 m
1 min = 60 s, so 33 min = 33 * 60 = 1980 s
The formula for speed is distance/time. So, we divide the distance by the time to get the speed.
Speed = 5000 m / 1980 s = 2.525 m/s
So, the speed of the jogger is approximately 2.5 m/s. Therefore, the correct answer is (b) 2.5 m/s.
