Answer 2

Answer:

ɢɪᴠᴇɴ:

Ron walks 22.5m in 5s

ᴛᴏ ꜰɪɴᴅ:

Ron's speed

ꜰᴏʀᴍᴜʟᴀ:

$\tt\bf\purple{Speed = \frac{distance}{time}}$

ꜱᴏʟᴠɪɴɢ:

${\bf{Speed =\frac{22.5}{5} }}$

${\bf{➺ \: \frac{225}{10} \div 5}}$

${\bf{ ➺ \: = \frac{225}{10} \times \frac{1}{5} }}$

${\bf{➺ \: \frac{\cancel 225}{10} \times \frac{1}{\cancel 5} }}$

${\bf{➺ \: \frac{\cancel 45}{\cancel 10}}}$

${\bf{➺ \: \frac{9}{2}}}$

$\tt\bf\red{\frac{9}{2} = 4.5 \: metre \: per \: second}$
