Question

A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours

Answer 1

We can write proportion as:

`\frac{\mathbf{30\:miles}}{1.5\:hours}=\mathbf{(x\:miles)/(4\:hours)}`

Explanation:

A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours

Proportion:

A proportion is used when two ratios are equal. It can be written as a/b=c/d

In our case we have:

a= 30 miles

b = 1.5 hours

c = x miles

d = 4 hours

We can write proportion as:

`\frac{\mathbf{30\:miles}}{1.5\:hours}=\mathbf{(x\:miles)/(4\:hours)}`
