Question

How many degrees does the minute hand covers in,
same time, in which the hour hand covers 20° ?
(a) 150° (b) 200° (c) 180° (d) 240°​

Answer 1

Step-by-step explanation:

correct answer is 200° hence option B is correct!

Answer 2

Clock

(d) 240°

As we know that in twelve hours, hour hand covers $360\textdegree$.

So, in one hour, hour hand will cover   $\frac{360\textdegree}{12}=30\textdegree$

Hence, time in which hour hand covers $20\textdegree \ is \ 40 \ minutes$.

A minutes hand covers $360\textdegree$ in 1 hour or 60 minutes,

Hence measure of angle it covers in 1 minutes $=\frac{360}{60}=6\textdegree$

So, measure of angle it will move in 40 minutes will be  $40\times 6=240\textdegree$

Hence, 240° will be covered by minutes hand in 40 minutes or the in the same  time in which hour hand covers 20°.
