Step-by-step explanation:
Given :Ant crawls at the rate 2\frac{1}{6}
6
1
ft /min
=\frac{12+1}{6}
6
12+1
ft
=\frac{13}{6}
6
13
ft
Distance: 5\frac{1}{5}
5
1
ft
=\frac{25+1}{5}
5
25+1
ft
=\frac{26}{5}
5
26
ft
Time taken =\frac{Distance}{Speed}
Speed
Distance
=\frac{26/5}{13/6}
13/6
26/5
\frac{26*6}{5*13}
5∗13
26∗6
Dividing numerator and denominator by 13
=\frac{12}{5}
5
12
=2\frac{2}{5}
