Step-by-step explanation:
Answer:
1.125 h = 1h 7.5 min = 1 h 7 min 30 sec
Step-by-step explanation:
John makes 1/1.5 work per h.
His partner makes 1/4.5 work per h.
Together they make (1/1.5 + 1/4.5) = (3/4.5 + 1/4.5) = 4/4.5 work per h.
They will work
1 : 4/4.5 = 4.5/4 = 1.125 h = 1 h + 0.125 h = 1h + 0.125h*60min/1h =
=1h 7.5 min = 1 h 7 min 30 sec
