if john wallked 50 miles than mira,how many miles do you think mira walked if they both walked a total of 290 miles.

Answers

Answer:

Mira = 95 miles

Step-by-step explanation:

Given

John walked 50 miles than Mira

The total miles walked is 290

To find

If John walked 50 miles more than Mira and the total miles walked including Mira is 290, then divide 290 by both of them. Once that is done, don't evenly distribute the miles to them. Because remember, John walked 50 miles more than Mira. So we just distribute this with John having 50 miles more. By subtracting 50 from Mira's share and give it to John

Solve

Divide 290 by 2

290 ÷ 2 = 145

Subtract 50 from Mira's share and give it to John

Mira's 145 - 50 = 95

Add that 50 to John's 145

John's 145 + 50 = 195

Therefore, John ran 195 miles and Mira ran 95 miles.
