First you take the 20 hours it took for the 3 service calls... 20/3=6.67. Then you multiply 6.67X7.5=50.025 hours.
Okay the scale for this equation is each inch equals 30 miles. SO to get how many miles 4.5 inches equals to, we have to multiply 30 by 4.5, and the answer we get is 135.
I hope this helps!
