×3.
For this you can write equations for your business and your friend's. For your's it would be y=10x-25 and for your friend's it would be y=13x-55. Now at this point you can just plug in numbers until you match up. Your answer would be 10, if you want to you can plug it in to check.
1 mile ≈ 1.6 km
5.067 km ≈ 5.067÷1.6 ≈ 3.2 miles
time travelled = distance ÷ speed
time travelled = 3.2÷225
time travelled = 0.0142 hour = 51.2 seconds
