Answer:
165km
Step-by-step explanation:
If Gina leaves now and drives at 66km/h she will reach Alton just in time for her appointment
Now:
Distance=Speed X Time
D=66 X t=66t.....(I)
If she leaves in 40 minutes,and she must get there at the same time, her new drive time will be:
t hours - 40 minutes
=(t-40/60)hours=( t-2/3) hours
Her Distance this time
D=90(t-2/3)=90t-60.....(ii)
Since the distance to Alton does not change, we equate (I) and (ii)
66t=90t-60
60=90t-66t
60=24t
t=2.5 hours
From equation (I)
Distance=66t=66X2.5=165km
Distance to Alton is 165km.

Answer:
1.135 or 17.5%
Step-by-step explanation:
√58 ≈ 7.616
√42 ≈ 6.481
7.616 -6.481 = 1.135
√58 is about 1.135 greater than √42. This is about 1.135/6.481 = 17.5% of the value of √42.
__
√58 is about 1.135, or 17.5%, greater than √42.
