A drivers distance varies directly as the amount of time traveled. After six hours, a driver had traveled 390 miles. How far had the driver traveled after 4 hours?

4 is 2/3 of 6, so he traveled

2/3 of 390 = 260 miles

you can use a simple proportion

6/390 = 4/x

6x = 1560

x = 260

or

it looks like he is traveling at 65 mph

so in 4 hours he would go 260 miles
