Question

Myra takes 2hours to plant 50 flower bulbs. Francis takes 3 hours to plant 45 flower bulbs. Working together, how long should it take them to plant 150 bulbs.

Answer 1

Answer:37 and half hrs

Explanation:

This is what I get

Myra: 50/2= 25 bulbs/hr.

Francis: 45/3= 15 bulbs/ hr

25+15= 40/hr. Together per hr

Need to find 150 bulbs how many hrs

40/1=150/t

40t=150

T= 150/4

T= 37.5

37hrs and 1/2
