Question

HELP I only need these two problems answered

2. Arturo can run 1 3/4 miles in 1/4 hour.
what is his speed in miles per hour?
How many miles can Arturo run in 3 hours

Answer 1

Formula d = vt

1 3/4= 1.75

1/4=0.25

So now plug into equation

To find v first to find per hr.

v = (1.75 miles) / (0.25 hrs) =

7 miles per hr

Distance per hr

d = (7 miles/hr)(1 hr) = 7 miles

In 3 hrs ?

d = (7 miles/hr)(3hr) = 21 miles
