Answer:
1. Given: distance = 90 meters; time = 7 secs.
Required: speed = ?
Equation: speed = distance / time
Solution:
[tex]90 \div 7 = 12.86 [/tex]
Answer: 12.86 m/s
2. Given: distance = 400km; speed = 85km/hr
Required: time = ?
Equation: time = distance / speed
Solution:
[tex]400 \div 85 = 4.71[/tex]
Answer: 4.71 secs.
3. Given: distance = 600,000m; speed = 110 m/s
Required: time = ?
Equation: time = distance / speed
Solution:
[tex]600000 \div 110 = 5454.54[/tex]
Answer: 5,454.54 secs.
4. Given: distance = 1700m; time 1800 secs.
Required: speed = ?
Equation: speed = distance / time
Solution:
[tex]1700 \div 1800 = 0.94[/tex]
Answer: 0.94 m/s
5. Given: time = 7mins. = 420secs.; speed = 6m/s
Required: distance = ?
Equation: distance = speed x time
Solution:
[tex]6 \times 420 = 2520[/tex]
Answer: 2,520m
