A car left Point A at 7:30 am and arrived at Point B, 162 miles away at 10:30 am. What was its average speed in miles per hour?
andre [41]
The formula for average speed is,

S= Total Distance Covered / Total Time Taken

In the given problem, 

The total distance covered is 162 miles.
Since only the times are given, we have to determine how many hours did the car traveled from 7:30am to 10:30am.

To get the number of hours: First, subtract the hours, then the minutes. Hours: 10-7=3 
Minutes: 30-30=0

Therefore,

S = 162miles/3hrs
S = 54miles/hr

The average speed of the car is 54miles/hr.

A crane lifts a load of bricks of weight 20 000 N to a height of 10.0 m. Calculate the work done or energy transferred by the cr
Oxana [17]

Explanation:

here we have mass(m);20 000N in kg will be 9.8kg

acceleration due to gravity (g): 10m/s

height (h) : 10m

so work done will be,

W=mgh

9.8x10x10

980joules

Issac and Blaise decide to race. They both start at the same position at the same time. Issac runs at 2m/s but decides to take a
FromTheMoon [43]

Let the Blaise runs for time "t" to complete the race

so the total distance he moved is given by

d_1 = 1* t

Now Issac runs for time t = "t - 2*60"

because it took rest for 2 minutes

d_2 = 2*(t - 120)

now it is given that Blaise wins by 10 m distance

d_1 - d_2 = 10

1* t - 2*(t - 120) = 10

t - 2t + 240 = 10

t = 230 s

now the distance moved by Blaise is given by

d_1 = 1*230 = 230 m
