The angle between hour and minute hand in 4:20 is 10 degrees. For a minute, the hour hand rotates by 30/60 = 1/2 degrees. hence, for 20 minutes it rotates by an angle of 20*1/2 = 10 degrees.
- - He runs 1.5 meters each second.
- Solve:
Divide 30/20
<span>=1.5
</span>To answer this we will divide the amount of meters by the amount of seconds. Then your answer will be the amount of meters Earl runs per second. Then we will check our work. Lets do it:-
30 ÷ 20 = 1.5
1.5 meter per second.
CHECK OUR WOK:-
1.5 × 20 = 30
<span>We were </span><span>RIGHT!!
</span><span>So, </span><span>1.5 meters per sec.</span>
