Answer:

[tex]13.51\ \text{s}[/tex]

Step-by-step explanation:

[tex]s[/tex] = Average speed of Sandra = [tex]7.4\ \text{m/s}[/tex]

[tex]d[/tex] = Distance Sandra ran = [tex]100\ \text{m}[/tex]

Time is given by

[tex]t=\dfrac{d}{s}[/tex]

[tex]\Rightarrow t=\dfrac{100}{7.4}[/tex]

[tex]\Rightarrow t=13.51\ \text{s}[/tex]

The time it takes Sandra to run the given distance is [tex]13.51\ \text{s}[/tex].
