Question

The distance is cyclist travels as proportional to the time she spends cycling. she travels 4 miles in 1/4 hour. Write an equation to show the relationship between the distance in travel ,D, and our sisters cycling ,h,

Answer 1

D = 16h

where
D = distance in miles
h = time in hours

Explanation:

Cyclist travels 4 miles in 1/4 hour
So her speed in mph = 4 ÷ 1/4

When you divide by a fraction, flip and fraction and multiply

4 ÷ 1/4 = 4 x 4/1 = 16 mph

So in 1 hour cyclist travels 16 miles

Equation is
D = 16h

where
D = distance in miles
h = time in hours
