Blanca jogged 8 days last month she jogged 1.25 miles on each day and burned 140 calories per mile while jogging how many calori
xz_007 [3.2K]

Answer:

140p calories

Step-by-step explanation:

Bianca is said to have jogged km 8 days, while also completing 1.25 miles every day. First, we calculate the total number of miles Bianca jogged in total, and that is

8 * 1.25 = 10 miles

Therefore, Bianca jogged a total of 10 miles the previous month.

Again, it is said that Bianca burned 140 calories per each mile she jogged and were asked to find the total calories that was burnt.

If Bianca burns 140 calories per mile, then she must have burnt 140 * 10 calories in 10 miles.

Therefore, we conclude that Bianca burnt 1400 calories.

Hey There!

Here is your answer:

First write the equation down:

-3 4/5 ÷ -3 1/6

Then put the mixed fractions into whole numbers:

-3 4/5= 5×-3=-15+4=-11= -11/5
&
-3 1/6= 6×-3=-18+1=-17= -17/6

Now right the new problem:

-11/5×6/-17

Now multiply:

-11×6=-66
5×-17=-85

Which means -66/-85 is your answer!

Hope this helps!
