Question

Find the product. List the units.
3/4h × 19 mi/1/4 h =

Answer 1

57 miles

Explanation:

First, do 19 ÷ 1/4. This is the same as 19 × 4 which is 76. Then do 3/4 × 76. 76 ÷ 4 = 19 and 19 × 3 is 57. The unit is miles because the two h's cancel out.

Hope this helps!

Answer 2

3/4 h times 19mi / 1/4 h
= (3/4)(19/(1/4) (h)(mi/h)
= (3/4)(76) mi
= 57 mi

or, 3/4 hrs ÷ 1/4 hrs = 3 hrs
and 3(19) = 57

or, 19 mi/(1/4)h = 76 mph
you are doing this for 3/4 hrs, so (3/4)(76) = 57
