find the constant of variation. Leon drove 100 miles in 2 hours. How far can he drive in 2 hours and 40 minutes?

Question

has to do with direct and inverse variations.

Answer 1

Distance = rate x time

 

D = r T  where D is the distance, t is the time and r is the FIXED rate of speed.

 

100 = r (2)  

 

r = 100/3 = 50 mph

 

40 minutes = 40/60 = 2/3 hr

 

2 hours and 40 minutes = 2 and 2/3 hours = 8/3 hours

 

50 * 8/3 = 400/3 = 133 and 1/3 miles
