DeSean and his family need to get to grandma's
for Christmas lunch by noon. If they are 120 miles
away at 10 a.m., what speed do they need to go?

Relax

Respuesta :

60 mph

There are 2 hours between 10 a.m. and noon, so you would divide the miles by however many hours they have left. 120/2 equals 60. So they have to go 60 mph if they want to make it there in 2 hours.
