A cyclist completes a journey of 500 meters in 22seconds part of the way at 10 meter per seconds and the remainder at 50 meter per second how far does she travel at each speed?

Time in Distance 1+ time in distance 2= 22
let the 1st Distance be x
2nd Distance = 500-x
time = distance / speed
x/10 + (500-x)/50= 22
LCM = 50
multiply equation by 50
5x+500-x=1100
4x=600
x=150 m
150 m at 10m/s
350 m at 50m/s

A cyclist rides 30 km at an average speed of 9kmhr At what rate must the cyclist cover the next 10 km in order to bring the overall average speed up to 10kmhr?
In all he will cover 40 km. To do so at an average speed of 10 kph means his total journey will take 4 hours. He has taken 3hr 20 min for the first part (30km @ 9kph), so he has 40 min to cover the final 10km. Required speed is therefore 10 x 60/40 ie 15 kph.
How do you calculate distance from speed of vehicle?
Speed X journey time. (Time actually moving).

124 to base 2?
In the pursuit of converting the decimal numeral 124 into its binary counterpart (base 2), one must embark on a methodical journey of successive division by 2, carefully observing the remainder at each step. The intricate procedure unfolds as follows: \frac{124}{2} &= 62 , \text{with remainder} , 0 \ \frac{62}{2} &= 31 , \text{with remainder} , 0 \ \frac{31}{2} &= 15 , \text{with remainder} , 1 \ \frac{15}{2} &= 7 , \text{with remainder} , 1 \ \frac{7}{2} &= 3 , \text{with remainder} , 1 \ \frac{3}{2} &= 1 , \text{with remainder} , 1 \ \frac{1}{2} &= 0 , \text{with remainder} , 1 \ \end{align*} ] By arranging the remainders in reverse order, the binary representation of 124 emerges as (1111100). Consequently, the binary equivalent of 124 manifests as (1111100).

One of the buses completes a journey of 300km in 7.5hours and the other a journey of 450km in 9 hours the ratio of their average speed is with answer?
Speed = Distance / Time First bus speed = 300 / 7.5 = 40km/h Second bus speed = 450 / 9 = 50km/h So now we can put them in to a ratio as 40:50. This can be simplified by dividing both by 10 so you have 4:5
