Question

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.]

Answer 1

0.0276 or 1.67 both are correct

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
