If X equals 39, y equals 58 and the measure of AC equals four units what's the difference in length between segments AB and AD round your answer to the nearest hundredth A: 0.74 units
B: 1.17 units
C: 1.64 units
D: 2.14 units

9 p.m.

Step-by-step explanation:

Given:

Start time = 5 p.m.Henry made = 60 cranesGordon made = 20 cranesHenry's speed = 30 cranes/hGordon's speed = 40 cranes/h

To find:

The time Henry and Gordon make same number of cranesSolution

Let the required time = x

For Henry:

60 + 30x

For Gordon:

20 + 40x

Since they require the same time and same number, we have:

60 + 30x = 20 + 40x40x - 30x = 60 - 2010x= 40x= 40/10x= 4 hours

The start time was 5 p.m., we need to add 4 hours to this to get 9 p.m.

At 9 p.m. they will get the same number of cranes
