Answer 2

Answer:

B

Step-by-step explanation:

We know,

$time \: = \frac{distance}{speed} \\ t = \frac{100}{60} \\ = > t = \frac{5}{3} hr \\ = > t = 1 \frac{2}{3} hr$

We know, 1 hr = 60 min.

Thus, ⅔hr:

$1hr = 60min \\ \frac{2}{3} hr = 60 \times \frac{2}{3} mn \\ = 40min$

Thus, Time Taken = 1hr 40 min. (Ans.)
