Answer:
Morning's average rate = 50 mph, and Afternoon's average rate = 25 mph.
Step-by-step explanation:
Suppose he drove 150 miles for X hours, then his average rate in the morning was (150/X) mph.
Given that he spent 5 hours in driving.
And he drove 50 miles for (5-X) hours, then his average rate in the afternoon was 50/(5-X) mph.
Given that his average rate in the morning was twice his average rate in the afternoon.
(150/x) = 2 * 50/(5-x)
150/x = 100/(5-x)
Cross multiplying terms, we get:-
150*(5-x) = 100*x
750 - 150x = 100x
750 = 100x + 150x
750 = 250x
x = 750/250 = 3.
It means he spent 3 hours in the morning and 2 hours in the afternoon.
So morning's average rate = 150/3 = 50 mph.
and afternoon's average rate = 50/(5-3) = 25 mph.

Answer:
$18360
Step-by-step explanation:
Since, the value decreased by 40%, the price is (100-40)% of 34000
= 60% of 34000
= 60/100 * 34000
= 60 * 340
= 20400 --- (Price after first year)
Since, the value decreased by 10%, the price (100-10)% of 20400
= 90% of 20400
= 90/100 * 20400
= 90 * 204
= $18360
