Walking Time
1. **State the problem:** Jasmine takes 120 steps in 4 minutes, each step is 8 dm long. We need to find out how long it will take Jasmine to walk 60 meters.
2. **Convert step length:** Each step is 8 decimeters (dm). Since 1 meter = 10 dm, each step length in meters is:
$$8 \text{ dm} = \frac{8}{10} = 0.8 \text{ m}$$
3. **Calculate total distance walked in 4 minutes:**
Jasmine takes 120 steps, each 0.8 m long, so total distance:
$$120 \times 0.8 = 96 \text{ meters}$$
4. **Find walking speed:**
Speed is distance divided by time. Time is 4 minutes.
$$\text{Speed} = \frac{96 \text{ m}}{4 \text{ min}} = 24 \text{ m/min}$$
5. **Calculate time to walk 60 meters:**
Time is distance divided by speed.
$$\text{Time} = \frac{60 \text{ m}}{24 \text{ m/min}} = 2.5 \text{ minutes}$$
**Final answer:** It will take Jasmine 2.5 minutes to walk 60 meters.
