Question

a cashier at the local bank is expected to serve 12 customers every hour.in the past 15 minutes, he served 4 customer's. assuming that the cashier continue to work at the same rate, wil he meet his goal.

Answer 1

There are four 15-minute intervals in an hour. If the cashier served 4 customers in one 15-minute interval, then he would serve 4 x 4 = 16 customers in an hour.

Since the cashier is expected to serve 12 customers every hour, he will meet his goal and serve more customers than expected if he continues to work at the same rate.
