Mr. and mrs. storey drive 3200 miles in all during their vacation. mr. storey drove 3 times as many miles as mrs. storey how many miles did mr. storey drive how many miles did mrs. storey drive

This can be solve by establishing equations.

let x be the miles mrs. storey drove

y be the miles mr storey drovee

the first equation is

y = 3x

second equation

x + y = 3200

x + 3x = 3200

4x = 3200

x = 800 miles mrs storey drove

y = 3x = 2400 miles mr storey drove
