Bob paints three flowers in four minutes. At this rate, in how many minutes can he paint five flowers

Show all work!!!!!

so first you need to work out how long it would take for him to paint 1 flower. you do this by dividing 4 by 3.
4/3 = 1 1/3
next you work how long it takes to paint 5 flowers so you times 1 1/3 by 5.
1 1/3 x 5 = 6 2/3 minutes
this equals 6 minutes 40 seconds as 2 thirds of a minute = 40 seconds

He paints 3 flowers in 4 minutes. So you need to calculate what time it takes him to paint 1 flower
3 flowers = 4 minutes
1 flower = (4 * 1) / 3 - 4/3
So Bob paints a flower every 4/3 minute
So the time required to paint five flowers = 5 * 4 / 3 = 20/3 minutes
Goodluck!

rate = 3 flowers per 4 minutes
= 3/4 flowers per minute

inverse rate = 4/3 minutes per flower

time required for five flowers = 5*4/3 = 20/3 = 6.67minutes (or 6mins and 40secs)

3 flowers in 4 minutes

4 minutes=4*60=240 seconds
3 flowers in 240 seconds

80 seconds per flower

5 flowers=400 seconds=6 minutes 40 seconds
or
6 2/3 minutes

or
20/3 minutes

3 Divided by four is 0.75 (one flower takes 0.75 mins )
0.75 times 5
3.75 minutes
approx 4 mins

6 mins 36 secs
