Answer:

t2 = 2.8 hours

Step-by-step explanation:

The distance is the same for each velocity.

Formula

d1 = d2

d = r*t

Givens

r1 = 140 miles / hour

t1 = 3.2 hours

r2 = 160 miles / hour

t2 = ?

Equation

r1*t1 = r2 * t2

Solution

140 * 3.2 = 160 * t2

448 = 160* t2

448 / 160 = t2

t2 = 2.8 hours
