Afamily's vacation destination is 850 miles from their home. they travel by car 6 hours on the first day of their trip. their average speed is 45 mph. the next day they travel 7 hours, averaging the same speed. how many miles are left for the family to travel?

The distance traveled is equal to the product of the speed and the time. For the first day,
                                      d = (45 mile/h)(6 h) = 270 miles
On the second day,
                                      d = (45 mile/h)(7 h) = 315 miles
The total distance traveled after 2 days is equal to 585 miles. Subtracting this value from the given distance will give us an answer of 265 miles. 

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
