The average speed of a car is 1 4/5 times the avg speed of a bike. A tractor covers 575km in 23hrs. How much distance will the car cover in 4hrs if the speed of the bike is twice speed of the tractor? | [
"460 km",
"320 km",

The speed of a bus in an hour = 25 × 2 = 50 km
The speed of a car in an hour = 9/5 * 50 = 90 km
So, the distance covered by car in 4 h is
90 × 4 = 360 km

A florist has 2 azaleas, 4 buttercups, and 5 petunias. The florist puts two flowers together at random in a bouquet. However, the customer calls and says that she does not want two of the same flower. What is the probability that the florist does not have to change the bouquet? | [
"43/55",
"17/55",
"8/11",
"38/55"
] | D | The probability that two of the same flowers were chosen:
P(AA) = 2/11 * 1/10 = 2/110
P(BB) = 4/11 * 3/10 = 12/110
P(PP) = 5/11 * 4/10 = 20/110
The sum of these probabilities is 17/55
P(two flowers are different) = 1 - 17/55 = 38/55

If a store adds 20 chairs to its current inventory, the total number of chairs will be the same as three-halves the current inventory of chairs. If the manager wants to increase the current inventory by 50%, what will the new inventory of chairs be? | [
"160",
"100",
"140",
"60"
] | D | Explanation:
Let’s say t = total current inventory of chairs. The first sentence states that 20 + t = (3/2)t. First solve for the current inventory:
20 + t = (3/2)t
20 = (3/2)t − t
20 = (1/2)t
40 = t
The manager wants to increase this by 50%.
50% of 40 is 20, so the new inventory will be 60.
