Question

Traveling at 55 mph, how many minutes, rounded to the nearest whole number, does it take to drive 310 miles from Boston to Syracuse?

Answer 1

(310 mi)/(55 mph)*(60 min / 1 hr) = 338.181818 . . . .

rounds to 338 minutes

Answer 2

we know that

`speed=(distance)/(time)`

Solve for the time

`time=(distance)/(speed)`

in this problem

`speed=55(miles)/(hour) \\ \\ distance=310 miles`

substitute in the formula above

`time=(310)/(55) \\ \\ time=5.64\ hours`

convert to minutes

`5.64*60=338.4\ minutes =338\ minutes`

therefore

the answer is

`338\ minutes`
