Answer
Standard labour rate per = $4.8 per hour
Step-by-step explanation
Labour efficiency variance is the difference between the actual time taken to achieve a given production output less the standard hours allowed for same multiplied by the standard labour rate
Standard labour rate = Efficiency variance/ Difference in hours
Difference in hours = Standard hour - Actual hours
= 46,000 - 45,000
= 1000 hours
Standard rate = 4,800/100o hours
= $4.8 per hour
