Acyclist travels 90.0 kilometers in 6 hours. what is the cyclist average speed?

15Kmph

Explanation

What I did to get the answer was divided 90 by 6 so kilometers divided by hours or any amount of time including minutes(to help with any other questions like this) and I got the answer 15 and then added my kilometers and hours which is also called mph so 15kmph.

Hope this helps!!

if you answer my question i will answer yours

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
