A man travels by a car from Town A to Town B, a total distance of x km/h. He finds that the time for the journey would be shorte

Vesnalui [34]

The question is incomplete. The complete question is :

A man travels by a car from town A to town B, a total distance of 100 km at an average speed of x km/h. he finds that the time for the journey would be shorter by 25 minutes if he increases his average speed by 12km/h. Find x ?

Solution :

It is given the that the distance between town A and B is = 100 km

His initial average speed is = x km/h

His increased average speed is = 12 km/h

Time is shortened by = 25 minutes

So according to the question,

$\frac{x \ km/h}{100\ km}-\frac{12 \ km/h}{100 \ km} = 25$

$\frac{x-12}{100}=25$

x-12 = 2500

x = 2512

nick have collection of 80 cars.3/5 of his toys are bus.the rest are cars and bike.the number of cars are the three time the num

stiks02 [169]

Answer:

24 cars

Step-by-step explanation:

out of 80 toys, 3/5 are buses- 80 * 3/5 is 48 so there are 48 buses

80 - 48 is 32, 32 of the rest of the toys are cars and bikes

we know that there are 3 times as many cars than bikes, so to find out how many cars and bikes there we can do 3n + n, where n is the number of bikes it also equals 4n

32 = 4n; n = 8

there are 8 bikes, so there are 24 cars
