Quantity & Rate

From the question, we are to determine how many total installations they would have completed

• For the technician

If the technician can complete an installation in 1.5 hours

Then,

In 60 hours, the technician will complete $\frac{60}{1.5}$ installations

$\frac{60}{1.5}$ = 40

Therefore, the technician would have completed 40 installations

• For the less experienced colleague

If it takes the less experienced colleague 2.5 hours to complete an installation

Then,

In 60 hours, the less experienced colleague will complete $\frac{60}{2.5}$ installations

$\frac{60}{2.5}$ = 24

Therefore, the less experienced colleague would have completed 24 installations

Hence, the total installations they would have completed is 40 + 24 = 64 installations
