Answer:
64 miles
Step-by-step explanation:
Number of miles driven in 45 minutes = 48 miles
We need to find how many miles will the truck drive drive in one hour. Since the rate is the same, the distance covered in each minute remains the same.
Number of miles driven in 1 minute = miles
Since, 1 hour = 60 minutes, we can write:
The number of miles driven in 1 hour (60 minutes) = miles
This means the truck driver can drive 64 miles in an hour.

You can find this by adding the 3 distances together and multiplying by 3. Also remember to watch the units as 500m = .5km.

Ben's estimate gives 7 g of nickel; the actual amount is 8.03 g.
In 1 g of the substance, there is 0.52 g of copper and 0.25 g of zinc; this gives
0.52+0.25 = 0.77 g of the substance.
The remaining part of the substance is nickel:
1-0.77 = 0.23 g of nickel.
Using Ben's estimate, 0.2 g of nickel per gram of substance, we have
0.2(35) = 7 g of nickel in 35 g of the substance.
The actual amount is 0.23(35) = 8.03 g of nickel in 35 g of the substance.
