Question

Dimitri normally blinks an average of 21.3 times per minute. How many times will he blink in 2.8 minutes? If he blinks 78.5 times per minute when he is nervous, how many times will he blink in 1.38 minutes while he is nervous?​

Answer 1

Simply multiply these together. Rate and time together.
21.3*2.8 = 59.64 normally
78.5*1.38 = 108.33 when nervous
