Aperson takes a trip, driving with a constant speed of 89.5km/h, except for a 22min rest stop. if the person's average speed is 77,8km/h (a.) how much time is spent on the trip and (b.) how far does the person travel?
need finding the starting point to this equation

Part a)

Part b)

Explanation:

Speed of the trip of the person is given as

here let say the time taken by the person for the trip is "t" min

so the total distance moved by the person in above time is given as

so we will have

now the average speed for the whole trip is given as

now we have

now we have

Part b)

Total distance moved by the person is given as

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
