A 6th grade student can complete 20 multiplication facts in 1 minute. If he works at the same rate, how long should it take him to complete 35 multiplication facts? [Type your answer as a decimal number.]

0.0276 or 1.67 both are correct

Step-by-step explanation:

so if he can complete 20 multiplication facts in 1 minute that means that 15 minutes take the time 35 seconds to 50 seconds lets cut that into 40 seconds  so 20+15=35 so one minute and 40 seconds

= 0.0278 hours  = 1.67 minutes  = 100 seconds

For 00:01:40  0 hours 1 minutes 40 seconds  Steps to Calculate Hours   0hr+1min×1hr60min+40s×1hr3600s =0hr+0.0167hr+0.0111hr=0.0278hr

Steps to Calculate Minutes
