Question

The distance to your brother's house is 481 miles, and the distance to Disneyland is 518 miles. If it took 13 hours to drive to your brother's house, how long would you estimate the drive to Disneyland to take?​

Answer 1

Brothers house = 481 miles dived by 13 hours = 37 miles per hour
Meaning 1 hour = 37 miles

Difference between brothers house and Disneyland = 37 miles

37 miles = 1 hour

Disneyland = 13 from brothers house + 1 hour from 37 extra miles =14 hours

It would take 14 hours to drive to Disneyland.

Answer 2

364/7 = 260/d

Cross multiply.

364d = 1820

d = 5 hours

Miles per hour, mph = miles/hour

364 miles/7 hours = 52 mph

260 miles/52 mph = 5 hours
