Jan left her home and drove for 5.2 hours due north at a rate of 60 miles per hour. After visiting a friend, she drove due south
Andreyy89

Answer:

180 miles

Step-by-step explanation:

Going North

<em><u>Formula</u></em>

d = r * t

<em><u>Givens</u></em>

r = 60 mph

t = 5.2 hours

d = ?

<em><u>Solution</u></em>

d = 5.2 * 60 = 312 miles north

Going South

<em><u>Givens</u></em>

r = 55 mph

t = 2.4 hours

<em><u>Solution</u></em>

d = r * t

d = 55 * 2.4

d = 132

Distance from home

Formula: Distance from home = Distance North - Distance South

Distance North = 312  -   132 = 180 miles

Luba_88 [7]

Answer:

Step-by-step explanation:

A complete circle has 360 degrees

So

300 + 32 + b = 360               Combine the left

332 + b = 360                       Subtract 332 from both sides

b = 360 - 332

b = 28
