Spike generally finishes 25% of his work in 1 hour, before taking a break for 30 minutes. If he has already spent 1 hour on the task with a 30-minute break, how much more time does he need to finish the rest of his work?
Answers
Answer:
3 1/2 hrs
Step-by-step explanation:
Given,
Spike generally finishes 25% of his work in 1 hour, before taking a break for 30 minutes.
25% of work in 1 hours
25%=1 hr
If he has already spent 1 hour on the task with a 30-minute break,
so he worked for only 30 minutes
1 hr=25%
1/2 hr=x%
x=25/2
x=12 1/2% worked in 30 mins
remaining work is 100-12 1/2=175/2%
12 1/2 =1/2 hrs
175/2=x hrs
25/2*x=175/2*1/2
x=7/2
x=3.5 hrs
