Question

At top speed, a rabbit can cover 7 miles in 12 minutes. If a rabbit could continue at this rate indefinitely, how long would it take the rabbit to cross the 220-mile expanse of the Mojave Desert?

Answer 1

Answer:

6 hrs 17 min and 8.57 sec

Step-by-step explanation:

Since, the rabbit could continue at the given speed, the ratio of Distance to Time taken is constant.

That is, $\frac{d1}{t1} = \frac{d2}{t2}$

$=>\frac{7}{12} = \frac{220}{t2}$

$=>t2 = 220 . \frac{12}{7} min$ = $220 . \frac{12}{7} . \frac{1}{60} hrs$ $=\frac{44}{7} hrs$ $= 6\frac{2}{7} hrs$

$= 6 hrs \frac{120}{7} min$ $= 6 hrs 17\frac{1}{7} min$ $= 6 hrs 17 min 8.57 sec$
